Why Is My Fridge Not Cooling?

Common Causes and What You Can Do

If your refrigerator is running but not cooling properly, don’t panic. This is a common problem, and in many cases the cause can be identified quickly. Below are the most frequent reasons why your fridge may stop cooling — and what you should do next.

1. Dirty Condenser Coils
Condenser coils release heat from your refrigerator. When they are covered with dust or pet hair, the fridge can’t cool efficiently.

What to do:
Unplug the fridge and clean the coils with a vacuum or brush. This should be done at least once or twice a year.

2. Blocked Air Vents
Cold air must circulate freely between the freezer and fridge compartments. If vents are blocked by food, cooling will be uneven or stop completely.

What to do:
Check inside the fridge and freezer and make sure nothing is blocking the air vents.

3. Faulty Evaporator Fan
The evaporator fan circulates cold air throughout the refrigerator. If it stops working, the freezer may stay cold while the fridge warms up.

Signs:

Freezer cold, fridge warm
No fan noise when the door is closed
Solution:
This usually requires professional repair.

4. Defrost System Failure
If the defrost heater, thermostat, or control board fails, frost can build up on the evaporator coils and block airflow.

Signs:

Heavy frost in the freezer
Fridge slowly losing cooling
Solution:
A technician should diagnose and repair the defrost system.

5. Bad Door Gasket
If the door seal is damaged or loose, warm air enters the fridge, making it hard to maintain temperature.

What to check:
Close the door on a piece of paper. If it slips out easily, the gasket may need replacement.

6. Thermostat or Control Board Issues
A faulty thermostat or electronic control board may prevent the fridge from maintaining the correct temperature.

Solution:
These parts require testing and replacement by a trained technician.

7. Compressor Problems
The compressor is the heart of your refrigerator. If it’s failing, the fridge may stop cooling entirely.

Signs:

Clicking noises
Fridge not cooling at all
Important:
Compressor issues should only be handled by professionals.

 When Should You Call a Professional?
If basic checks don’t solve the problem, continuing to run a malfunctioning fridge can lead to food spoilage and higher energy bills. Professional diagnosis ensures the issue is fixed correctly and safely.
