Evaporator Coils Are Frozen
When your fridge stops cooling, the Evaporator coils have probably frozen. To thaw them, remove the freezer door from the fridge and look at the coils. If they’re covered in frost, you’ll need to wait a few days (1-2 days in most cases).
Broken Evaporator Fan
Your fridge’s not working. It’s not cooling, it’s making a squealing/ rattling noise, and the noise only gets worse as you open the fridge. In this instance, the cause is a faulty evaporator fan. A stuck or broken evaporator fan usually makes a high-pitched noise, and is located by the coils.
Dirty Condenser Coils
Your refrigerator is not getting cool enough. It’s possible that your condenser coils are dirty, which is an issue that needs to be addressed immediately. If this is the problem, your coils will never be able to disperse heat from the fridge. Dirty coils can even cause the thermostat to cut power to the coils if they overheat.
Faulty Thermistor
The thermistor is important for monitoring the air temperature inside the fridge. If it’s defective, the refrigerator won’t cool properly and it might seem like a more technical problem. If you suspect a faulty thermistor, please contact a fridge repair expert as this is a difficult fix.
Faulty Condenser Fan
The back of the fridge has a panel that is easy to open. If you have problems with cooling, go behind the panel and look for two parts: the compressor and the condenser fan. The compressor turns on if the thermostat demands more cooling. It does so by drawing warm air across coils.

Frozen Evaporator Coils
The most common reason why a refrigerator is not cooling is a problem with the evaporator coils. Over time, evaporator coils can become covered with ice, which prevents the coils from working properly. If the coils are covered in ice, the ice will need to be defrosted to fix the problem.
Defective Evaporator Fan
If the refrigerator is not cooling and is making squealing noises with increased vibration, the evaporator fan is likely defective.
Bad Condenser Fan
The condenser fan draws in outside air to cool the condenser coils and the compressor. The air is then sent out through the base grille. If the condenser fan is not working, it will cause the compressor fan to overheat and stop working properly. A defective condenser fan can also cause the compressor to not turn on.
Other Possible Causes
If the evaporator coils, evaporator fan, or condenser fan are not responsible for the compressor not cooling, the start relay, condenser coils, or thermistor should be checked to further diagnose the problem.

What is a control board on a mini fridge?
The control board acts as the “brain” of the fridge, as it saves power, dials specific temperatures, and engages power cool cycles if the door has accidentally been left open.
1. The condenser coils might be dirty
One possible reason why your mini-fridge is not cooling is if the condenser coils at the back of your fridge are dirty. When they get covered in dust, they have to work overtime to try and keep your mini-fridge cool, and sometimes this won’t be enough, and your fridge won’t be able to cool down to a low enough temperature.
2. The condenser fan might be defective
The next reason to investigate is a defective condenser fan. The condenser fan blows warm air over the condenser coils to prevent them from frosting over. If the fan stops working, the coils won’t stay cool, and your fridge might not be able to cool down to a low enough temperature.
3. The evaporator fan might be faulty
Depending on the specific make and model of your mini-fridge, it might have an evaporator fan. This fan helps to transfer cold air from the small freezer compartment in your mini-fridge into the main fridge area. If it stops working, your mini-fridge might struggle to cool.
4. The compressor might be faulty
The most important component within your mini-fridge is the compressor. The compressor produces refrigerant that is then pumped around your fridge to ensure it stays cool. If your mini-fridge doesn’t cool, the compressor is the one of the first components you need to rule out as the cause of the problem.
5. The start relay might be defective
The start relay works in conjunction with the start winding to help the compressor operate. If it becomes defective, your mini-fridge will struggle to stay cool.
6. The temperature control thermostat might be faulty
The temperature control thermostat monitors the temperature in your mini-fridge and then directs voltage to the evaporator fan motor, the compressor, and the condenser fan motor as needed. If it stops working, your whole fridge will stop cooling.
7. The start capacitor might be faulty
The purpose of the start capacitor is to assist the compressor to start up. If it stops working, the compressor won’t be able to start up, and your mini-fridge will fail to keep cool.
