Many fridges have a small fan near the compressor, at the back bottom of the cabinet, that pulls air across the condenser coils. It is easy to forget about, but when it fails the fridge can overheat, cool poorly and put the compressor at risk.
Fridge Condenser Fan Not Working: The Short Answer
A condenser fan usually stops or slows because of a worn motor, dust and debris jamming the blades, a damaged blade or perished rubber grommets, or a wiring or control fault. The signs are a warm fridge, a very hot compressor, and cooling that gets worse on hot days. With the fridge switched off at the wall, you can clean dust from the fan area, but a failed motor needs replacing by a technician.
Common Questions About Condenser Fans
Does every fridge have a condenser fan?
No. Fridges with condenser coils on the back or inside the side walls often rely on natural airflow. Fridges with the condenser underneath usually have a fan.
Where is the condenser fan?
Usually behind the rear access panel at the bottom of the fridge, next to the compressor.
When should it run?
On most fridges, the condenser fan runs whenever the compressor runs. If the compressor is running and the fan is not, there is a problem.
What happens when it stops?
Heat is not removed from the condenser, so pressures and temperatures rise. The fridge cools poorly, the compressor overheats and may cut out on its overload, and power use goes up. Left too long, it can shorten compressor life. See signs of a bad compressor.
Why has it stopped?
- worn motor bearings or failed windings
- dust, lint or debris jamming the blades
- a cracked or loose blade
- perished rubber mounting grommets causing noise and vibration
- a wiring, connector or control board fault
Why is it noisy?
Dirty blades, worn bearings and hardened grommets make condenser fans rattle, buzz or chirp. See common fridge noises.
Can I check it myself?
With the fridge switched off at the wall, you can remove the rear access panel if it is designed for that, vacuum dust from the fan and coils and check the blade turns freely. Testing the motor involves electrical work and should be left to a technician.

How Technicians Fix It
A technician checks whether power reaches the fan, tests the motor, inspects the blade and grommets, cleans the condenser and replaces the motor if needed. They will also check the compressor has not been damaged by overheating.
Keep Your Condenser Fan Healthy
- vacuum the condenser area every six to twelve months
- keep the back of the fridge clear of bags, boxes and lint
- leave ventilation space around the fridge

Frequently Asked Questions
What happens if the fridge condenser fan stops working?
The fridge cools poorly, the compressor overheats and may cut out, and power use rises. It should be repaired promptly to protect the compressor.
Should the condenser fan run all the time?
On most fridges it runs whenever the compressor runs, not all the time.
How do I clean a fridge condenser fan?
Switch the fridge off at the wall, remove the rear access panel if designed for it, and vacuum dust from the fan and coils.
