What Causes Refrigerator to Stop Cooling?

You open your fridge on a sweltering summer day, hoping to consume a glass of ice-cold juice. Unfortunately, your refrigerator is not cooling. What a dreadful situation! Not only will this, but the items in your refrigerator also be affected due to this bad condition.

There is a multitude of reasons that can cause a refrigerator to stop or reduce cooling. This is an unwanted condition but almost every fridge-owner would have dealt with it at least one time. Taking care of your refrigerator properly can assist in lowering the chances of this occurring.

Here are some of the commonly known reasons that may affect the cooling of the refrigerator in your home.

1. Frosted Evaporator Coil

In the freezer section of the refrigerator, there are evaporator coils and a rotating fan. Excessive frost formation on the evaporating coils can cause bad cooling. As time passes, frost builds up on the coils and fan. The evaporator coils become insulated as frost accumulates on them.

The rotating fan is incapable of drawing air over the frosted coils as a result of this. Because of the ice over the coils, there might still be some cooling, but there is no flow of air over the coils. For optimal cooling inside the fridge, this ice must be eliminated by hand defrosting or automatic defrosting.

2. Defective Evaporator Fan

The fan distributes cold air from the cooler to the refrigerator's other chambers. When the evaporator fan fails to operate, the cold air within the food segment cannot disperse. As a result, the freezer remains cold, but the food portion does not.

3. Out of Order Compressor

The refrigeration cycle's core is a compressor. When it fails to function correctly, the whole cooling mechanism is halted. The compressor's function is to squeeze refrigerant vapors from reduced pressure cold vapors to higher pressure warm vapors.

This compressed refrigerant moves into the condenser in the shape of warm elevated-pressure vapors, where it is compressed into a high-pressure fluid. After that, the liquid passes into the evaporator coil, where it disappears and melts to a reduced-pressure vapor.

The refrigerator is kept cool by air flowing over the cooling coils. As a consequence, when the compressor fails, the refrigeration system does not even begin.

4. Thermostat Is Turned Up

This may seem self-evident, but unintentionally raising the thermostat lowers a refrigerator's potential to generate cool air. A refrigerator's optimal temp range is between 35 and 38 ° F.

Please ensure the thermostat is fixed somewhere in this area, and double-check the temperature with an independent thermometer to confirm it's correct.

5. Dirt Insulated Condenser Coils

During the transformation of elevated-pressure warm refrigerant to the low-pressure cold refrigerant in the condenser, a huge amount of heat is lost. Heat does not move out of the coils correctly when the condenser coil is filthy and filled with waste. This heat condenses within the refrigerator, reducing cooling efficiency.

6. Faulty Condenser Fan

A condenser fan in your fridge extracts hot air. As a result, when it spoils, the hot air is trapped within the appliance and cannot escape. As a result, the fridge's temperature rises. The condenser fan will not function correctly if the fan motor or blades are damaged.

7. Blocked Air Vents

The capacity of a refrigerator to cool depends on adequate airflow. The machine would not be able to disperse cool air if the ducts on the back of the system are covered by food, liquids, snow, or garbage.

Carefully check if you can sense cool air flowing behind the fridge. If there is low or no ventilation, the issue is most likely due to a jammed vent. However, eliminating the obstruction is a simple solution.

8. Substandard Start Capacitor

The compressor gets a boost from a start capacitor when it gets going. The compressor will not operate if this capacitor is damaged, and the refrigeration process will not begin to cool the fridge.

These are the most common things that can cause your refrigerator to stop cooling. Maintain the cleanliness of your fridge will automatically help you to keep your appliance working for extended periods.

We expect that this information will help you in protecting your refrigerator from any damages. If you find your fridge not working well or has stopped cooling completely, then call an expert to resolve the issue. Do not try to set the things on your own, as it might lead you to an even bigger problem.
