Introduction
A refrigerator that won’t cool is more than an inconvenience—it’s a race against spoiled food and costly repairs. Whether your fridge is barely cold or completely warm, the issue often stems from a few common culprits. In this guide, we’ll walk you through how to diagnose and fix a refrigerator not cooling, using OEM replacement parts to ensure your appliance runs like new.
Common Causes of Refrigerator Cooling Issues
-
Dirty Condenser Coils
Dust and debris on the coils force your fridge to work harder, reducing cooling efficiency.
Fix: Unplug the fridge, locate the coils (usually at the back or bottom), and clean them with a coil brush. -
Faulty Evaporator Fan
This fan circulates cold air. If it’s broken, cold air won’t reach the fridge compartment.
Fix: Test the fan by spinning it manually. If it’s stuck or noisy, replace it with a new refrigerator evaporator fan. -
Malfunctioning Thermostat
A broken thermostat can’t regulate temperatures properly.
Fix: Use a multimeter to test the thermostat’s continuity. If it’s defective, install a replacement refrigerator thermostat. -
Compressor Failure
The compressor is the heart of your fridge. If it’s humming but not cooling, it may need replacement.
Fix: Check for power to the compressor. If it’s dead, you’ll need a refrigerator compressor replacement.
Pro Tips for Success
-
Always unplug the fridge before repairs to avoid electric shock.
-
Use OEM parts (like those in our Refrigerator Parts category) for reliable performance.
