The freezer fan, also called the evaporator fan, sits behind the freezer back panel and pushes cold air through the freezer and into the fridge. When it stops, both compartments can warm up, often with the fridge section going first.
Freezer Fan Not Working: The Short Answer
A freezer fan usually stops because ice has built up around the blades, the fan motor has worn out, a blade is damaged, the door switch is faulty, or the control board is not sending power to it. Ice around the fan usually points to a defrost fault. A worn motor typically squeals before it fails. Most freezer fan faults are repaired by replacing the fan motor and fixing any underlying defrost problem.
Signs the Freezer Fan Has Failed
- the fridge section is warm while the freezer is colder
- no airflow from the vents
- squealing, chirping or grinding from the freezer, often changing when the door opens
- silence where you normally hear a fan
- frost building up on the back wall
Common Causes
Ice around the fan blades
Ice can jam the blades. The fan may scrape, then stop. This usually means the defrost system has failed. See fridge defrost problems.
Worn fan motor
Fan bearings wear over time. A squeal that gets louder when the freezer door is open is a common early sign. The motor usually needs replacing.
Damaged blade
A cracked or bent blade throws the fan out of balance and causes noise. Blades are replaced rather than straightened.
Door switch fault
Many fridges stop the fan when the door opens. A faulty door switch can keep the fan off.
Control board or wiring fault
If the motor tests fine but receives no power, the control board or wiring may be at fault.

What You Can Check
- Open the freezer and listen near the back panel with the door switch pressed.
- Look for heavy frost on the back wall.
- Check nothing is blocking the vents inside the freezer.
- If there is heavy ice, a full manual defrost can restore airflow temporarily while you book a repair.
Removing the back panel and testing the motor involves electrical parts and should be done by a technician.
How We Fix It
Our technicians test the motor, check for power at the fan, check the door switch and board, inspect the blade and look for the defrost fault that often comes with it. Fixing both the fan and the defrost cause stops the problem returning. See also fridge not cooling but freezer works.

Frequently Asked Questions
How do I know if my freezer fan is not working?
The fridge warms while the freezer stays colder, there is no airflow from the vents, and you may hear squealing or nothing at all from behind the freezer panel.
Why does my freezer fan make noise?
Worn bearings cause squealing, and ice around the blades causes scraping. Ice usually points to a defrost fault.
Can a fridge work without the freezer fan?
Not properly. Without the fan, cold air does not circulate and the fridge section warms up.
