Signs of Low Refrigerator Gas

Signs of Low Refrigerator Gas - Appliance Repairs in Port Elizabeth
Russel Hobbs Refrigerator
Domestic and Industrial refrigerator give you different indicators or signs when it is low on Gas (refrigerant). In this post I am just going to cover domestic fridges/freezers and in another post I will do industrial fridges (walk in refrigerators).

Refrigerant starvation can lead to expensive repairs

Signs of Low refrigerator Gas

1. The first signs of low gas; your food starts to freeze up in the fridge section of your refrigerator. Salad leaves turning black (frostbite), tomatoes are frozen in the vegetable draw, milk and eggs are also frozen in the fridge. (This also the time when most people think it is the refrigerator-thermostat that has gone on the blink – but I will explain more about this situation in another post)
 
2. The second sign; the fridge is developing a ice buildup on the condenser plate and a faint smell is present

3. Big block of ice is forming in one corner of the refrigerator and freezer section is making too much ice. It becomes difficult to keep the freezer door close. It is about this stage you start hearing a clicking sound
.
4. At stage four your fridge is not making any ice anymore but the inside back is still sweating a lot with water dripping continuously. The moldy smell has also increased. The freezer section is now really over-icing. At this stage you also start breaking the inside-draws because they are now freezing soled and are stuck. Clicking sounds start to increase.  In another post I will explain more about that clicking sound. For now if you don’t speak Refri-lingo the "clicking" sound means "Help!"                                                        
5. At stage five your refrigerator is close to dying a horrible death, it becomes noisy and stays off for long period. The frozen food becomes soft and everything starts to defrost.

If you notice any of the above mentioned signs in your refrigerator don’t let the compressor and refrigerator suffer. Switch it off straight away then get a professional to come analyze your refrigerator.

I hope this information has added some value to your life

Cheers!

Refrigerator not Cooling -

Refrigerator not cooling

The invention of the defrost cycle has lead to the now very popular Frost Free Refrigerator. The new generation refrigerator is suppose to leave you free from defrosting your freezer every other month.

"That is how it is suppose to work in the perfect world"

Airflow is crucial for your fridge/freezer to function optimally

All cold air is generated in Freezer compartment. The cold-air are then forced into the fridge compartment threw small ducting (tubes) with a Fan - called Evaporator Fan.

The most common reason for the unit to stop cooling is when the Freezer section is freezing-up. It happens threw the collection of moister that accumulates on frosting plates inside freezer. The more moist air allowed to entering freezer area, the more frost (ice) would accumulate.

With a manual chest or upright freezer you know you have to manually defrost the unit yourself, once there is too much ice build up inside the freezer. With the Airflow type Refrigerator you expect that it should function correctly and defrost it-self.

Unfortunate in a normal household things happen.
1. Somebody forgets to close the door properly and the unit collects too much moister in the airflow channels - Causing it to freeze up.
2. The door gaskets are not cleaned regularly then stop keeping cold inside compartment..

Warning Signs

• Refrigerator units like Defy, Samung and Whirlpool has a small orange light (led) flashing
• The ice or goods on the top shelve in the Freezer cabinet starts to defrost.
• Suspicions odors inside fridge section
• Milk is the first to go off.

When it comes to storing food for long periods your box-type freezer is still the best because when a upright Freezer gets open cold air falls out. When this happens a gush of hot air fills the unit making the temperature fluctuate.  Some foods cannot be stored for long period of time in these upright Frost Free units due to the short rise and fluctuation in temperature - when the heater-elements come on in the defrosting cycle.

The 3 main components in the defrosting system

1. Thermostat or Electronic sensor – it regulates the temperature
2. Heater – generates thermo energy to defrost evaporator
3. Timer or Electronic printed circuit Board – keeps track of the cycles

Possible Fix

Check if there is an ice-build up between the bottom freezer shelf and the 3 shelve. (Inside the unit at the back plate) If there are an ice build up switch the unit off and let it defrost (manually). When defrosted – turn refrigerator back on again.
