Bad Defrost System

Excessive accumulation of ice on the freezer surface is not suitable for the cooling process. Therefore most of the refrigerators come with a defrost system.

The defrost system heats the evaporator coil and other cooling elements to melt the chunked frost on the surface.

But when the defrost system is not functioning correctly, it results in excessive frost build-up. Consequently, it creates poor airflow which leads the freezer to insufficient cooling.

This is not a problem that you can solve at your home. So you have to consult a proper servicing.

Thermostat Issue

The thermostat makes the fridge cool down according to the requirement. But when the thermostat shows tantrums, the freezer may not get cool enough or may not get chilled at all.

So this is another problem that may have happened to your refrigerator. You will need a replacement in this case.

Frosted Evaporator Coil

The evaporator coil helps to absorb the heat from the foods in the fridge; therefore, it plays a significant role in the cooling process.

Otherwise, you can keep the refrigerator off and defrost it.

Low Refrigerant Level

The refrigerant is the most essential part of the cooling process of the refrigerator. It absorbs the heat from your food and releases it outside so that your food can stay fresh.

But if the refrigerant is lower than its required level, it will no longer make your freezer cool.

So this is another noticeable problem when the freezer is not cooling down.

To refill the refrigerant, you need to consult the experts.

Compressor Issue

The compressor is another most critical part of your refrigerator. Therefore, any issue in this part can lead your freezer to malfunction or shut down properly.

To get your compressor fixed, you have to show it to some expert. So hurry and get it solved.

Issue In The Condenser Fan

The condenser fan helps the refrigerant in the condenser coil to cool down. Therefore, it is a vital part of the refrigeration system.

So if there is any issue with the fan or the fan motor, it will not be able to do its job correctly. This will lead to lousy cooling.

So, you can check whether the blade is running correctly or not. You can try to move it with your hand.

If it does not run freely, there might be some issue with the motor. The afterward deeds you can leave to the expert.

The start capacitor is a device that helps the refrigerator compressor to start and run to a stipulated time. It controls the compressor.

Any issue in the start capacitor will lead to the malfunctioning of the compressor.

And without a doubt, it will harm the cooling process. If you see some weak spark or any change in the building of the start capacitor, consult an expert.

Start Relay Issue

Again this is a support system of the compressor. The start relay helps the compressor to start.

So, if there is a problem with the start relay, the compressor will not participate in the cooling process of the refrigerator.

You can detach the start relay from the compressor and give it a shake to observe any rattling sound. If you observe any sound, chances are the start relay is broken.

In such circumstances, you need to replace it.

Door Seal Issue

The door seal has a significant role to act in the cooling process of the refrigerator. It helps the cool air captured in the fridge.

A weak door seal will leak the cool air. So, immediately change the door seal if there is an issue.

These were the most critical issues that can affect the cooling capacity of your refrigerator. Some other issues are inadequate food storage and broken door switches.
