Here the most common reasons your refrigerator isn’t cooling:

Refrigerator Not Cooling?

The problem may be simpler than you realize. The first thing to check is your refrigerator’s temperature control settings. Perhaps it got accidentally shifted. If so, shift your refrigerator to a colder setting to see if that helps.

Another possible issue is the food load. Ensure that there isn’t too much food near the air vent. If your fridge or freezer is packed too full, you may be blocking the air vent and preventing cold air from entering the fresh food compartment.

Examine your refrigerator’s gaskets to ensure they are sealing properly. A poor seal could cause the refrigerator to leak cool air. Repair or replace them if necessary.

Also, check the state of the refrigerator’s condenser coils. If they are significantly dirty, they won’t regulate properly and will make refrigerator work harder to keep itself cool. Use an appliance brush to give the coils a sufficient cleaning and you could see a dramatic increase in your refrigerator’s performance.

Causes Of Refrigerator Not Cooling

If none of those adjustments do the trick, the problem is likely due to a faulty part. The most common faulty parts when your refrigerator isn’t cooling are:

  • Evaporator fan motor: This motor is crucial in the circulation of cool air into your unit. If your freezer is is still functioning properly while your refrigerator won’t cool, this a sign that it may be a problem with the evaporator fan motor. The fan should be checked for any obstructions. If the fan is not flowing properly (w/ no obstructions), is excessively noisy, or the motor doesn’t display continuity (which is tested with a multimeter), it needs to be replaced.
  • Condenser fan motor: This is another part that is crucial to your refrigerator’s cool air circulation, except likely neither the refrigerator or freezer will be cooling properly. It should be examined similarly to the evaporator fan motor. The condenser fan blade will need to be checked for obstructions and the motor for continuity.
  • Start relay: If the start relay is faulty, it can cause problems with the refrigerator’s compressor (which circulates refrigerant through condenser and evaporator coils). It should tested for continuity and replaced if necessary.

While those are the most common faulty parts, it’s also possible that there’s a continuity issue with the temperature control thermostat, start capacitor, or thermistor. This is not quite as common as problems the condenser fan motor, evaporator fan motor, and start relay, so those should be checked first.

When all the above have been ruled out as the culprit, it is likely a more in-depth repair. In these exceedingly rare cases, the temperature control board, compressor, or main control board would need to be replaced.
