It can be really frustrating if your refrigerator starts getting warmer for seemingly no reason. If you notice the fridge’s temperature is consistently warmer than the setting you’ve chosen on the thermostat, then there may be a part that isn’t working properly. Let’s take a look at several different components of your refrigerator’s cooling system and see if we can pinpoint why your refrigerator is not cooling properly.
Check the Coils
The condenser coils circulate refrigerant and are responsible for dissipating heat. If the coils get dirty, they will not be able to get rid of the heat efficiently, thereby making it very difficult to cool down the air inside your refrigerator. These coils are typically found behind or below your refrigerator. Take a look and make sure there isn’t a lot of dust or dirt buildup on them. If there is, carefully vacuum or wipe them down to ensure they can get rid of the heat properly. This is a common reason for a refrigerator not cooling that can be resolved fast.
Check the Condenser Fan Motor
The condenser fan causes air to quickly pass over the condenser coils and help remove the heat they’re dissipating. This helps keep the coils cool and enables them to do their job efficiently. If the fan is not working, the coils are not able to get rid of the heat and the fridge will not cool down properly. Make sure the fan is working and is not obstructed by dirt or debris. If the fan is unobstructed but not working, this could indicate a problem with the fan motor. If the fan blade will not even spin by hand, then it is likely the motor will need to be replaced. If the fan is working, you can also use a multimeter to check the fan motor’s continuity.
Check the Compressor
The compressor is the component that works to compress and circulate refrigerant through the evaporator and coils. If the compressor is not working, refrigerant will not flow through the coils and therefore your fridge will not cool down. This is not a common problem, and it is more likely for some of the other parts mentioned to be defective. If the compressor does need to be replaced, you will need to contact a licensed professional to handle the replacement.
Check the Start Relay
The start relay is a small device that provides power to get the compressor up and running. If the compressor is not running at all, or is only running intermittently, there may be a problem with the start relay.
Check the Thermistor
The thermistor senses the temperature in your refrigerator. It is connected to the temperature control board and helps determine when the temperature has fallen or risen over the temperature set by the thermostat. If the thermistor is not sensing properly, it will not report to the temperature control board correctly, which can cause deviations from the desired temperature.
