Appliance Thermostat

Appliance Thermostats

Stove and refrigerator Thermostats

Thermostats are nothing more than a on/off switch with a intelligence which can control a predetermined  temperature for Appliances like Refrigerators, Ovens, Microwaves, washing machines, tumble dryers and even GHD's has it.

Most people tend to think that a thermostat works the same as a water-tap; -

If you turn the thermostat setting higher more coldness or heat will flow.

Nothing can be more further from the truth

Refrigerator compressor and stove elements only work at 100% capacity - circulating refrigerant (gas) at full speed. The same with a oven element it only works full blast.

Once electric power is connected to a heating element it will go red-red hot till you cut the electricity by using a on/off switch(wall plug) or regulator( stove plate switch) and lastly a thermostat. Same with a compressor it only pumps gas full speed.
so you see there is no such thing as heating element or compressor operating on a slower
Appliance Thermostats

There are so many thermostat variouses on the market but I will just cover some of the more popular types we use in repairing everyday appliances.

I just need to get this out of the way first, a stove plate/element regulator (switch) is not a thermostat but I will tell more about them in another post.

Electronic temperature Probe for refrigerator

Kinds of thermostats

  • Mechanical thermostat; Used in Refrigerators and Ovens
  • Electronic thermostat(module); Fridges like Defy has them and the new generation ovens of samsung and whirlpool
  • Thermistor; used in GHD's, toaster, irons and kettles

Appliance thermostat Anatomy

  • Capillary; A Thin tub filled with gas which reacts with temperature changes 
  • Sensor probe: Attached to one end of the capillary tub one and connected to the unit you want to control.
  • Controller; Other end of capillary is connected to controls and the knob has number on it giving you the impression that you are increasing or decreasing "something" . . 
Well I hope this has given you something to think about and next time when you refrigerator over-ice or the oven over-tan the pie don't just assume that it is the thermostat that has gone on the blink.

Samsung Microwave Switches

Most microwaves has three micro-switches in the door which controls the flow of electricity and also acts as a safety mechanism. 

Never Ever-EVER stop the microwave cooking process by opening the door, rather press Stop button.

Energy Regulators

Stove Repairs in Port Elizabeth
Siebel Energy Regulators

Energy Regulators are Infinite switches that turns electric stove plates/ elements/ burner on and off. By turning the rotary knob to various setting it controls the temperature of the heating device (stove plates).

How an Infinite Regulator works

Inside the Regulator is a bimetallic strip that heats up when electricity passes through it. After a few seconds the heat causes the bimetallic strip to bend (warped) - then a spring-loaded control to open (cutting the power flow). Once the power is cut the bi-strip starts to cool down again, returning to its original position (Shape). When the bimetallic strip is back in its original shape the whole process starts over again.

The abovementioned mechanical actions is done on very petite scale and it cannot handle the heavy current of a stove plate or heating-element. The simmerstat (fancy name for regulator) needs the help of a more robust spring loaded switch or contactor that mirrors the actions of the little guy mention in the first paragraph.

Now who says the little guys has no Say? -  I will tell you more about the mighty contactors in a later post.

By turning the knob to its highest setting it will take longer for the little guy (bimetallic strip) to reach "cut-off (bend) and the heating device gets hotter


Mechanical switches/regulators generate a spark (arcing) everytime it make contact or switches on/off which can cause interference on a radio and electronic gadgets. However if this situation should ever occur, it is easy-peasy rectified with the help of suppressors.

As always I hope this has added some value to your thinking, should you need more leave a comment or contact me on Facebook.

Diagnosing Noisy Toploader Washing Machine

Appliance Repairs in Port Elizabeth

The reason for this post is to help you identify possible causes and solutions for a noisy Toploader washing machine. There are a couple of things that can causes a Toploader Washing Machine to become noisy and the noise mostly appears during a Spin-cycle. Everyday things like a bra-wire, coins or hair clips get stuck between the inner and outer drums of your Toploader washing machine will make a racket when washing machine goes into the spin-cycle.
Anatomy  of Toploader Washing machine undercarriage
There are two areas where the noise normally comes from in a toploader washing machine and that is from the drain pump or the inner washing machine drum. Actually there are more things could cause a noise (stabilizers) but they are so far and wide that I'm not even going to discuss them today. If they should ever come up you just drop me a line and we can chat about it.

Drain Pump 

You should hear a noise every time when the machine goes over into a drain cycle. All you have to do is open your drain filter hatch and remove all debary that is lodge inside the filter house-ing.

if the noise persists even after you have cleaned the filter, it means that the pump-pulsator is damaged and the drain pump needs to be replaced.

Noisy during Spin cycle

There are a couple of things that could causes the Washing machine to become noisy during the Spin-cycle.

  • Inner wash drum has detached from outer wash drum
  • Inner drum assembly (spider) has crack
  • Gearbox is busy failing
  • Center bearing is rusted and dry
  • Foreign object is lodge between inner and outer drum
Do the following exercise

Run the washing machine on the Spin cycle without anything in it 
  • If the noise are gone it means the inner drum spider assembly is cracked and needs to be replaced
  • If the noise are still there without a load in the washing machine it could be two things
  1. There is a foreign object logged in between the outer and inner drums. This is a easy fix and all you need is a set of "braai-tongs" and some pointer from me.
  2. Center seal has collapsed and water has leaked through the gearbox - onto the bearings. Tilled the washing machine about 45 degree backwards and let it lean against a wall. Get down on your knee and while you down there you can do two things;-  humble yourself, have some gratitude and be grateful for the luxuries of owning a washing machine. Secondly look for rust and water leaks.
When a toploader washing machine has rust markings in the centre it means that it is leaking from the centre seals. 
Speed Queen washing machines has a mechanical seal that can be replaced. 

Samsung and LG toploader washing machines normally springs a leak through the gearbox and seals are not available in South Africa which means you have to replace the whole gearbox assembly.
Whirlpool washing machines never leaks, actually I have had it once or twice that the agitator shaft seal would go and water leaks straight into gearbox

Defy toploader has the durability of the speed queen and whirlpools but are in the economical price range of the samsung's and Lg's, they hardly ever develop centre water-leaks. 

Lastly look for water streaks around around the edges on the outer casing of the washing machine because sometime this will tell you its not that serious and it is only a water hose that has perish.

Thank you for stopping and I hope you have found some value, should you need more - leave a comment below.

Remote gate Repairs

Remote Gate Repairs in Port Elizabeth

The biggest reason why remote gate motor fail can be prevented by performing a few simple tasks regularly.
Spiderweb covered control module

Simple Preventive maintenance tasks

  1. Grease the Wheels: 
All visible wheels should be lubricated regularly (once a month if you are staying at the coast like we here in Port Elizabeth). In the olden days we use to use oil but now you can buy a can of silicone spray or liquid grease. These canned products makes it so much easier and cleaner to lubricate the wheels.  Most gates has two wheels at the bottom and two stabilizer wheels on top.

      2.Pop the Top:

Remove the top cover of the gate-motor regularly to do a visible inspection of the inside. 

Look for the following 
  • Water streaks and marks - moisture on the electronic can cause havoc. 
  • Insects - If you see one you can be sure his friends are sleeping somewhere in the warm gate motor dome.  Crochers love to lunch on the printed electronic boards.
Ants on the other hand are gathers, they bring you food and stuff. I myself are a ant person - just love the little hardworking fellows. So don't use mean insecticide on them. Rather go for a more natural ways to make them move.  
  • Chalk-line around gate motor unit - ants hate getting covered with chalk
  • Cotton Balls dipped in peppermint essential oil - they don't like the smell 
  • Peppermint oil mixed with water in spray bottle have the little hallers move quick-quick
  • Some people also spray vinegar diluted with water but if you spray directly on them they will die.  Rather do not use this method
Weather damaged Gate-motor control  module
Did you know

The chemical progress (between positive and negative ions) inside a battery is slower once the outside temperature gets cooler.

If you are living in an area where the temperature drops very low at night it might be a good idea to install a lamp inside the gate motor dome that is connected to a temperature sensor. The lamp will turn once the temperature drops and heat up inside the gate motor dome so that the battery can perform at it optimal level.

You can buy these temperature sensor at most good hardware store. They are inexpensive and it is a easy DIY.

Ovens and Stoves Cleaning

Oven and Stove Repairs in Port Elizabeth

Dirty Defy stove controls

Here at All Appliance Repairs we always suggest not keeping your oven too clean. 
Ovens need a fatty/oily layer to protect the grooves and seams from moisture causing rust.

Defy Ovendoor covered in grease

Recently we had the pleasure of working on a extreme Dirty Defy Stove that even had me blinking and because I love appliances - seeing an appliance go into despair just breaks my heart.

Dirty Spiral Plate 

Too much fat buildup will have the opposite effect, instead of protecting - it allows the steam/spills to go underneath the buildup preventing moisture from evaporating causing the oven and plate-under cups (reflector cups) to rust even faster

Rusted Spiral Plate reflector cup
Don't get me wrong I'm not saying you should keep a dirty oven or stove in your home, I'm just suggesting that you take precautionary measures and leave a thin layer of fat/oil. It’s actually funny seeing some people’s faces turn to horror when I tell them their oven is too clean, some women even shiver in horror by the mere thought of a dirty Oven in their home.

Over the years I've had the honour to be rubbing shoulder with some of Port Elizabeth greatest Chefs, One thing I know from them is that the secret to a magnificent meal is in the equipment and the preparation. If your cooking equipment is dirty or if it works inconsistently, you will taste it in the end.

Tip: Never tell the cook his oven too clean!

Defy stove Hob can be lifted to clean

"I'm late, I'm late, I'm late." said the White Rabbit.

Modernday oven and stove cleaners are extremely aggressive, its made to give you instant cleaning-results.  (it's especially made for people with no-time-to-waste on cleaning their ovens because they must Earn-more to pay for regular oven replacements.) The Combination of aggressive oven cleaners, moist air and heat will get into the joints will get into joints/grooves making it rust.

The following Cleaning methods has stoot the test of time;

Bicarbonate of soda cleaning method          

  •  Mixed Bicarbonate of soda with Hot water so that it forms a paste. Then smear this paste onto the grease inside the oven and leave for a couple of hours. The past will soften the dirt and also absorb odours. Your might still need a little bit of elbow-grease but in the long run it is worth it. Some people say instead of water one should use white vinegar. Give it a try and let us know about this one.
  • Alternatively made a cleaning past with Lemon juice and bicarbonate soda is great to remove odours and minor grease in your microwave oven
  • Cooking oil or silicone spray will break up grease if dabbled over the dirty spot. This is especially recommended for glass and stainless steel ovens or hobs.  appliances will shine after cleaning with this method.

The above cleaning methods with leave your appliances fresh and clean without the harsh chemical smell to breathe-in.

Enjoy the cleaning but above all enjoy the baking

Ps. Did you know baking soda is a type of salt - sodium carbonate plus sodium carbon dioxide

Refrigerator sides are Hot

Appliance Repairs in Port Elizabeth

Refrigerator sides are hot

Being warm on the outside is normal for a Refrigerator.
Commercial fridges even have heating elements fitted but Domestic Freezers and Fridges have warm pipes inside the cabinet walls circulating around the refrigerator.

How does it heat up happen

Refrigerant (gas) is circulated through the system by a compressor. The tubing that radiate heat are purposely installed inside the sides of the cabinet foam to emit heat from the gas while the compressor is working

When the compressor is off, the sides are cold.

Why the Heat
  • It helps to prevent condensation (sweating) and ice forming on the outside of the freezer, preventing rust
  • Keeps the fridge door gaskets soft
  • It also stops freezer door from icing up, preventing the door gaskets tearing upon opening

Reason for excessive heat

In summer when the outside temperature is higher, refrigerators-sides also tend to feel hotter than usual. We tend to rely more on our fridges for contentment in hot weather which means it get open more often. Every time you open the door all the cold air falls out and hot air rushes in, the compressor must work more often to get the content chilled again.

·  Refrigerator compressor runs more/longer than normal when:-

o Large quantities of warm food or beer was loaded into refrigerator
o Refrigerator has been off/storage for a time
In both these instances the sides should cool down once the inside load cools.

Possible Solutions and Preventive measures
  • ·         Make sure there is enough space at the back for ventilation
  •           Check that it’s clean behind refrigerator (the condenser coils).
  •           Pet hair, lint and dust will make refrigerator run warmer
  •           Move fridge to a cooler location - never near a stove or oven

As a last resort you could set up a desk fan behind the refrigerator but I think this is more for your own peace of mind.

Enjoy the summer

Samsung is Grey

Appliance Repairs in Port Elizabeth

Junkyard grey - Samsung no longer supply parts to back their Appliances, once the appliances are out of its warranty period the company are finish with you. So whatever you do,  Do not buy any Samsung Appliances again especially if you are staying in the Eastern Cape your samsung appliances has just become grey-junk

It seems Samsung SA just employing Ping-pong players and they are aiming to be the no 1 Ping-Pong company.

It has now been weeks since I have been trying to get answer from samsung but they are such good ping-pong players they just bounce you to the next Ping pong player. 

The ping-pong team main airheads are Peters and Chatt but don't bother they are completely unapproachable (returning calls are not in their scope of practice) or maybe they too busy working that they have no time for their customers. (i always thought customer are reason why one work)  

What went wrong

Its just so hard to comprehend when big branded appliances start going south.

Kelvinator, National, KIC, Hi Tachi, etc are all Appliance Brands that use to be great products like Samsung and are no-longer. These brand names are still been used by devious marketers  to quickly sell their inferior products to unsuspected consumers. Most of these products get imported from some place which you can't even pronounce and then a well know name get slap on them.

These dodgy has-been Appliance brands gets sold with no backup service like parts or professional consumer service department. (I really think this is where our government should step in to protect the South Africa's consumers)

Getting back to "What went Wrong" . . . .! "I don't know" 

I saw the same happening with Barlows and HiTachi before they went belly up with their appliances. They could not supply the trade with parts and their agents would strip "comeback appliances" for parts to fix appliances that is still under warranty. 

All I can say is . . . .

Rest in Peace Samsung

Preventative Maintenance Tips for your Refrigerator

Defy Side by Side refrigerator

Preventative Maintenance Tips for your Refrigerator 

Guest post by

Purchasing a new refrigerator can be quite a task. Researching the sheer number of types and brands can be quite a daunting task. First you have to decide the type of refrigerator that you want: French Door Refrigerator, Side by Side Refrigerator, or Bottom Freezer Refrigerator. After you select the type of refrigerator that you want, then comes a harder decision, the brand. Maybe you know someone that recently purchased a refrigerator and because they rave about their refrigerator, you select a similar brand. Or, maybe you google refrigerator reviews and select the “top” reviewed brand. However you end up selecting your refrigerator, at the end of the day you begin to realize the importance of conserving the investment of your time and money. If you already have a refrigerator, the importance of conserving its life and importance can’t be understated.

Enter Preventative Maintenance (PM)…….
So what is preventative maintenance? Preventative maintenance is performing maintenance on a piece of equipment so that the likelihood of failure is lessened. Don’t be afraid, of the word “maintenance”, because changing the oil in your car is also considered to be maintenance. If you change the oil in your car, then you have the ability to perform some of the Preventative Maintenance Items for your refrigerator. And like changing the oil in your car, you can always go to your local appliance repair shop to help you perform the PM items that you may be hesitant about. This will allow you to preserve your brand new or used refrigerator for as long as you can. Now, here’s the top 3 Preventative Maintenance Items that you can perform on your refrigerator. They won’t be in any specific order, these are just some of the important items that are easy to perform, but play a huge role in increasing the life of your refrigerator. 

You may already know some of these tips, but I will elaborate on the reasoning behind them. In my experience understanding the “why” of something helps you to better recognize the importance of accomplishing this task.

Top 3 Preventative Maintenance Tips

Clean the Coils in your Refrigerator. This tip is probably a popular one, but let’s dive into the reasons behind cleaning the condenser coils, the locations of these coils, and the frequency of cleaning these coils.  The condenser frequently has air passing over it. Debris, hair, dirt and etc., gets caught in the condenser coils from the room air. When this happens, the compressor will work twice as hard (or maybe more), to maintain the temperature that you have your refrigerator set. Because the compressor has to work harder, the service life will decrease causing it to fail prematurely. Now you have to call a repairman….
The condenser coils are mainly located in two areas on most all types of refrigerators: underneath the refrigerator and at the back of the refrigerator. If the condenser is underneath the refrigerator you should unplug the refrigerator, and with someone to assist, slightly tip the refrigerator over, so that the coils are visible. Note that you may have to remove the contents of the refrigerator. If the coils are located at the back of the machine, unplug the refrigerator and slide forward. There may be cardboard or a metal plate covering the area. Once the area is visible, you can use a vacuum with an attachment to clean the coils, and you can also use a condenser coil brush. This brush is sold in most appliance shops.
Lg Refrigerator Dirty back air vents

Depending on the amount of people, pets, and the cleanliness of your floors, this these coils should be cleaned every 3 months.

Inspect/Clean or Replace Door Seals/Gaskets. Here is another common preventative maintenance item that I’m sure you’ve heard about, but let’s look closer at the benefits, and the frequency of inspection etc. of your door seals. The door seals or gaskets are usually made of rubber with a magnetic strip and is found in inside the door frame. The primary purpose of a door gasket or seal is to ensure that the door is closed shut, ensuring that warm moist air won’t be able to get inside the refrigerator. This also ensures that the cold air generated inside the refrigerator is not allowed to escape. It is very difficult for your refrigerator to maintain cold temperatures inside when cold air is escaping and warm air is allowed to enter. This will cause the energy needed to maintain the set temperature to increase. This increase in energy will translate to an increased electric bill, as well as potential premature failure of refrigerator components due to a need in increased output. Seals should be inspected to ensure proper conditions. If the seals are damaged or beginning to fall off the frame they should be replaced immediately.

When you receive the seals that need to be replaced before installation make sure that gaskets are not twisted or warped. If needed use warm water or a hairdryer to make the gasket is as straight as possible. There are usually 3 types of installation styles for door seals. The first style is one in which the gasket is pushed into a groove around the parameter of the door. The second style is one in which the gasket is held behind a liner by a retainer lip found on the refrigerator. The last style of installation is by loosening the screws and fitting the gaskets between the inner and outer door panels. Once installed make sure that there is no gap between the gasket and frame, over time the door seals will flatten. Petroleum jelly can be used to ensure that the seals won’t bend near the hinged area.

If a new door seal is not needed, make sure that the gaskets are thoroughly cleaned. Debris can get caught in the rubber stopping the door from closing fully. The gaskets or door seals should be inspected every 2-3 months.

Check the Refrigerator’s Internal Temperature. This is probably a preventative maintenance item that is not as common as the prior two items. You should regularly check your refrigerator’s internal temperature to ensure little variation throughout the day. A food thermometer can be used to verify the consistency of the temperature over time. It would be a good practice to verify the temperature between 2-3 hour increments. During this time, it is important that the refrigerator door remained closed for the duration the increments. 3 trials should be enough to verify any fluctuations in temperature that may occur. If your refrigerator is running and the temperature has dropped only 3-5 degrees, the refrigerator’s cooling process is in great condition. If there are large fluctuations, the first two items, as well as other troubleshooting techniques may be needed. If there is any issue with temperature fluctuations, an appliance repair technician should be used to check the refrigerator’s functions.

These are just 3 of the main preventative maintenance items that can be of great help when it comes to preserving your refrigerator. Preventing problems from happening, is very important, and could end up being a great investment for your new or used refrigerator.

Hand Dryer repairs in Eastern Cape

Hand Dryer Repairs in Port Elizabeth

Electric hand driers! -  Best thing since the invention of sliced bread, they have elevated bathroom hygiene to new levels.  
I always get the shivers when I have to walk pass one of those bacteria invested waste-baskets overfilled with used paper towels – even worse are those rolled cloth towels. Somewhere along the line you have to touch where the previous visitor just did his “business”. Jugg! 
- Lets rather move on to what I actually what to tell you about in this post.  

Hand dryers are so convenience, just hanging silently on bathroom wall ready to spin into action as soon as you rub your hand underneath it. Like all modern day appliances the convince come at a price to the environment.

It is true Electric hand dryers do save tree's - but all those plastics and metal used to build them. Then there’s the electricity they use? In all fairness the new generation Hand Dryers uses much less electric energy that their older counterparts.
Printed circuit board (Pcb) of a hand dryer
One Handdryer that stands a little above the rest (paper/cloth towels and old school dryers) is Xlerator. Comparing the Xlerator to other new generation hand dryers I unfortunately cannot give you an accurate comparison because I haven't had much experience with the other brands. (The older generation handdryers - yes!) In our part of the universe (Eastern Cape) we don’t really see much of the other newer trade names

Like all Electric-Appliances, hand driers need periodic services. This is also the single biggest reason why they come in for repairs – “the dryer were never serviced or cleaned”! 

The inlet grill get clogged with fluff and then the motor starts running hotter than normal - Overheating! doesn't matter if it is a tumble drier or vacuum cleaner overheating is very bad for any kind of electric-motor. All you have to do is get your handyman to remove the cover and wash the little inlet grill  

Inlet grill of a hand drier

Personally I think the manufactures should have installed a removable filter grill at the in let.
Small electric motor carbon brushes and damage commutator

The second cause why electric hand dryer fail is Carbon Brushes. These little buggers are responsible for making the motor turn by allowing electric current to run through them into the commutators. The electric current creates a north and south pole in the motor. The little carbon brushes now push the commutator sections away - one cell at a time, creating rotation.

Once the carbon brush starts wearing-out, it stops making secure contact with the commutator. As you know when you have a loose or bad electrical connection excessive heat starts to develop in a unit. 

You can see in the above picture the commutator was burned black by the excessive heat.

Dishwasher Problems and Troubles

Dishwasher Repair in Port Elizabeth
Dishwasher not dispensing detergent

When opening a Dishwasher in anticipation of clean sterile dishes and cutlery but instead  the dishes are cover with smears and stain marks. That is a major let-down! 
Dishwasher are great machines when they work. . . . ! but when it starts giving inconstant results, it becomes a huge source of frustration. 
Lately we have been receiving a lot of inquiries about dishwashers giving inconsistent cleaning results. I have highlighted some of the most common problems my clients have with their dishwasher and possible solutions. 

Cutlery and Dishes has a stain residue on them when washed 
Most people use their dishwasher on after dinner and the machine remains close for the night then the following happens

  • Steam then tends to condensate on cutlery if dishwasher is left closed - leaving residue marks

Ø  Dishwashers should be opened after 20 minutes program has ended - allowing hot air and steam to escape
Ø  When dishwasher cycle is finished machine should at least be left closed for another 10 minutes

Detergent powder is not dissolving
·        Check spray arms for blockages in the little end jets
·        Was the dispenser chamber dry before inserting cube/powder
·        Was the cutlery and dishes pack so that it could have prevented the soap dispenser flap from opening

Dishes remaining wet at end of cycle
·        Dishes must be arranged so no water puddles are formed on cutlery
·        No salt in Dishwasher result in;
o   lime scale building-up on heater elements
o   which in turn effects the drying results
§  a descaler should be used to dissolve lime
·        To little rinse aid can also have an effect on the drying result

Dishes has smears and streak marks
Ø  Overdosing of rinse aid will results in streak marks at the end of a cycle 

Once you have tried the above advice and the problem still persists it means the machine has a default some were and you need a professional to open the Dishwasher up.

I do hope you have found some value in this post

Surge Protectors and Suppressors

All Appliance Repairs in Port Elizabeth

Electrical Filter is the layman's term for suppressors and surge protectors. Most good appliances has Surge protection unit build into them.

Microwave Oven Surge PCB

All Appliances in South Africa has been taking beatings and major abused from our National Electrical supplier with their inconsistent ("Loadshedding") power supply schedules.
Although the "loadshedding" has become less, we still have daily uncontrollable electrical spikes.

In South Africa and most other countries receive AC power (alternating current) from their national grid supplier. Like the names says "Alternating Current" - it means the power supply is alternating (like waves in the ocean) The voltage goes Up and Down. Sometimes it will spike at 300+Volts and then down to 180 Volts. In the RSA we use 220 volts, the USA and Europe use 110 Volts.

Surge spikes (also called transients) are measured in units of 10 -6 Second. Transients that cause havoc inside appliances normally are in the several hundreds range and a lightning strike goes into the Thousands.

Electrical Surges and Spikes are a fact of life and they will always be with us

This is the reason why all appliances need surge protectors and suppressors

TVSS (transient voltage surge suppressors)

These little devices  or commonly called SPD (surge protection devices) come in many different and sizes but for this simplicity I will only cover the ones you find and use in everyday Household appliances.
Washing Machine Electrical Line Filter that has exploded

Surge Diverter

The surge diverter relays (or blocks) a electrical spike above a certain voltage down to the ground. This normally creates a electrical short in your system but I will discuss this effect more in detail in another post.

Transient Voltage Suppressor

TVS's  is commonly used in Household All Appliances and it react to momentary voltage spike . Commonly known as voltage Zener suppress diott.

Metal-Oxide Varistors
Hoover PCB With MOV

MOV is more found in electronic circuit boards and TV, sounds systems and top range microwaves. The Mov's are fast and they respond to a voltage surge much quicker than any of his other suppressor buddy,s. Their main function is to protect the other electronic components  from a "over-voltage"

One can just keep on going about the many different types of suppressor and diott that is out there - like you also get a unit that is filled with gas.

OK, ok! I will stop now!

I do not want to risk losing you because of overexpose to boredom. My fascination might be toxic to your entertainment system.
Getting back to the reason why I am telling you about these little appliances (suppressors) is because of safety and also to tell you it doesn't always pay to be a cheapskate.

MOV has been Documented to Burn

Some electronic manufactures tend to be cheap when designing voltage protectors and the installation thereof.
Defy Dishwasher PCB overheated causing panel to meld

While the overvoltage might not be enough to blow the fuse or destroy the MOV, it does cause the PCB unit (printed circuit board) to overheat. The overheated MOV will eventually then start the fire.

The are many factors that separate the good manufacture from the not-so-good ones but here are a couple easy noticeable ones
  • Silicone wire is used or flame retardant materials (Defy appl use it in most of their units)
  • The surge PCB is installed in a remote area inside the appliance so that even if it catches fire it will not cause the whole appliance to burn
  • As a habit one should always try to fit and use surge protection units but there are so many dummy units out in the market place. It is very difficult to direct you from a distance what to look out for because on the outside they all look legit.
  • I would recommend is to find yourself a good electrical supplier (be careful for the national franchises because they buy in bulk from the east on "good deals") and also think twice next time when you buy cheap unbelievable deals. (they can make it so cheap because they schimp on necessary safety equipment). 
  • Always ask about the appliance backup service because after the supplier guarantee period has expired you could be stuck with an electrical item with no backup service.
