My refrigerator isn’t cooling

Diagnosing and repairing a refrigerator that isn’t cooling properly requires a few diagnostic steps. Here’s a general outline of what I would do:

1. Check the thermostat: I would start by checking the thermostat to make sure it’s set to the correct temperature and that it’s functioning properly. If the thermostat is malfunctioning, it may not be signaling the compressor to turn on, which could be causing the cooling issue.
2. Inspect the evaporator fan: If the thermostat is working properly, the next step is to inspect the evaporator fan. If the fan is not working, it won’t be able to circulate cold air throughout the refrigerator, which could be causing the cooling issue.
3. Clean the condenser coils: Dirty condenser coils can also cause a refrigerator to not cool properly. I would inspect the condenser coils and clean them if they are dirty. This can be done with a soft brush or vacuum cleaner.
4. Check the compressor: If the above steps don’t resolve the issue, I would then check the compressor. The compressor is responsible for compressing and circulating refrigerant throughout the refrigerator. If the compressor is not functioning properly, it could be causing the cooling issue.
5. Test the thermistor: The thermistor is a sensor that monitors the temperature inside the refrigerator and signals the compressor to turn on and off accordingly. If the thermistor is not functioning properly, it may be sending incorrect signals to the compressor, which could be causing the cooling issue.

Once I’ve diagnosed the issue, I would repair or replace any faulty components, such as the thermostat, evaporator fan, condenser coils, compressor, or thermistor, as needed.

It’s important to note that diagnosing and repairing a refrigerator that isn’t cooling properly can be complex, and it’s best to leave it to a trained professional like myself to ensure that it’s done correctly and safely.
