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

Disadvantages

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 marking 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 it 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.

Cheers!

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.

Do you have tips and advice on how to keep our little friends at bay and maintain your remote gate unit. Please leave us a comment below.

Happy remoting

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 thing 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

Cheers!
