For Why is my refrigerator not cooling but the freezer works fine?, start with "Check the air vent between freezer and fridge": Open the fridge section and look for a small vent (usually at the top or back). Place your hand near it—if no airflow is felt, the vent is blocked or the fan is dead. Stop DIY if the compressor is hot to the touch but not running. This is listed as a moderate recovery and usually takes about 1 hour.

help1. Understand the Problem

Refrigerators rely on a single cooling system; cold air from the freezer is circulated to the fridge section by an evaporator fan. If the vent is blocked by ice or debris, or the fan fails, the fridge won't cool properly. A defrost issue can also cause ice buildup that blocks airflow.

See what's happening and how to try the first recovery step.

1
Step 1: Clear any visible ice or debris
Clear any visible ice or debrisUse a plastic spatula to gently remove ice from the vent. Avoid using sharp objects that could puncture the wall.

Step 2: Access the evaporator fan
Access the evaporator fanUnplug the refrigerator. Remove screws from the back panel inside the freezer section to expose the fan.
3
Step 3: Test the fan motor
Test the fan motorSpin the fan blade manually. If it's stiff or doesn't spin freely, the motor bearings are seized. Check for voltage at the connector using a multimeter.

Step 4: Replace the fan if faulty
Replace the fan if faultyDisconnect the wiring harness, remove the mounting screws, and install the new fan. Reassemble the panel and plug in the fridge.

Frequently Asked Questions

Can a dirty condenser coil cause this issue?expand_more
Yes, dirty coils can reduce overall cooling efficiency, but they typically affect both sections equally.
How do I know if the defrost heater is bad?expand_more
If there's heavy ice buildup on the evaporator coils, the defrost heater or thermostat may be faulty.
Is it worth repairing an old refrigerator?expand_more
If the fridge is over 10 years old and the compressor is failing, replacement is often more cost-effective.
