Why is my Refrigerator Not Cooling?

The refrigerator had one job and it let you down. Your refrigerator is warm and your food and drinks are starting to smell and bacteria are beginning to grow. I’m sure it’s the last thing that you wanted to happen. Luckily, there is a way to fix this problem!

Broken Door Gasket/Seal Replace the broken door gasket/seal
Compress Not Starting Bad relay- Replace relay
Compressor Fan Won’t Start Replace the Capacitor
Defrost Timer Malfunctioning Replace the Defrost Timer or Control Board
Dirty Condenser Replace/ Clean the Condenser Coils and Fan
Temperature/Thermistor Set the temperature to colder

Air Damper (diffuser)

  • The Air damper is responsible for opening up and allowing the cold air from the freezer to blow into the fresh food section in the refrigerator. You may need to replace this if your freezer is cold but the refrigerator is warm.

Condenser Fan Motor

  • The Condenser Fan Motor circulates air through the refrigerator grille and helps to cool the compressor and condenser coil. Check to see if your condenser fan motor is operating correctly. If you hear any “clicking on and off,” noises from the compressor then it is operating correctly.

Condenser Tubing

  • The Condenser Coils are located under the refrigerator. If the Condenser Coils are dusty and dirty then they will not disperse heat efficiently. If they are dirty then it is time to clean them!

Control Board

  • The Control Board regulates the functioning of the unit, includes the defrost cycle times and cooling. If the control board is broken then it will stop sending the correct information to the cooling system. Test this last in your refrigerator.

Compressor

  • The Compressor compresses the refrigerant in your refrigerator which helps keep your food cool. If the motor is running but the temperature in your refrigerator is warm you may want to replace this part.

Door Switch

  • The Door Switch is located at the bottom of the refrigerator door. It is responsible for turning the light off and resumes cooling action when the refrigerator is closed. You have a faulty door switch the refrigerator will not cool properly.

Evaporator Fan Motor

  • The Evaporator Fan Motor propels the fan blade to circulate air around the coil kit in order to regulate the temperature. If your refrigerator is not cooling you may want to check your freezer. Make sure that the evaporator fan is working, if it is blowing cold air around then you’re in luck!

Frost Free Failure

  • It could be your defroster aka frost free failure is not doing its job. To check this, first, remove the access panel in the freezer (you will see the evaporator coils) if there is frost on these coils it will limit the amount of cold air to enter the refrigerator since it is blocking the evaporator fan motor.
  • Fan Blade: Check this while you’re at it. It can have frost on it and not operate efficiently causing the cold air to not enter the refrigerator.
  • Defrost Timer (it may be in a different location depeneding on the make and model of your refrigerator) Once you find it turn the screw like wheel in the middle with a screwdriver until the fridge turns off (you are officially in defrost mode, congratulations!) If the defrost heater turns on then you should replace the defrost time and thermostat.

Gasket/Seal

  • The door gasket/seal creates an air-tight seal around the refrigerator preventing warm air from entering. Make sure that there is no damage on your gasket of your refrigerator door, this can cause cold air to escape and warm air to enter your refrigerator

No Power/ Lost Power

  • You may have lost power and your refrigerator is not cold anymore. The best temporary fix is to keep your refrigerator door closed! If you have a generator you’re in luck, but if not be sure to keep those doors closed. You may also want to check your breaker box to see if that will turn your appliance back on. Or simply unplug and re plug in your appliance.

Thermostat/Thermistor

  • The Thermostat/Thermistor could be the difference between your refrigerator cooling and it being warm. To determine if the Thermostat is the problem, spin the thermostat from the lowest setting to the highest setting and listen for a clicking noise. If it is clicking then the thermostat is not defective. Did someone turn the thermostat temperature way down by mistake? Make sure that your thermostat is set at the correct temperature so your food and drinks stay fresh longer.
