If your refrigerator has stopped cooling properly, this article provides an overview of how to troubleshoot and fix some common refrigerator problems.
This step-by-step guide will show you how to troubleshoot a failing, warm refrigerator, identify the likely cause, and possibly even fix it yourself to save the cost of a professional repair. Even if you need a technician, you’ll be able to show them the problem directly.
Tools Required
- Socket/ratchet set
- Wire stripper/cutter
Materials Required
- Evaporator fan
- Condenser fan
Why Is My Refrigerator Not Cooling?
There are several possible reasons why your refrigerator may stop cooling milk and freezing ice cream properly. Before attempting complex repairs, try these simple fixes if your fridge is not getting cold:
- Make sure it is plugged in and receiving power. The light should turn on when opened.
- Check that the thermostat hasn’t been mistakenly turned down very low. You can install replacement thermostats easily.
- Confirm the vents along the freezer back aren’t obstructed by food packages, blocking airflow.
- Vacuum dust from the condenser coils under and behind the unit. Clogged coils reduce cooling.
- If your model has an exterior fan, ensure it spins freely and isn’t stuck. Unplug first and manually rotate the blades. The fan should run when the compressor cycles on. If not, see the repair guide below.

If you hear the compressor activate but feel little cold air within, the issue likely involves frost-clogged evaporator coils or a malfunctioning evaporator fan inside the freezer. A failing fan often squeals loudly when spinning up. Opening the door causes the shrieking to intensify if the fan is problematic. Locate your coils and fan by removing the interior freezer panel.
Replace the Refrigerator Evaporator Fan
Start repairs by unscrewing the freezer cover to access the evaporator and fan components. Watch for plastic caps concealing the screw heads.
Remove Fan Cover
If a protective fan cover is present, detach it by removing the fastener screws so you can reach the fan.
Remove Evaporator Fan
With the refrigerator unplugged, take out the mounting screws to fully detach the existing evaporator fan from the freezer housing.
Replace the Fan
Install the replacement fan by shifting over the mounting bracket and wires from the old assembly. Carefully connect the wiring using wire connectors and reinstall the fan bracket. Replace the freezer cover.
Replace the Refrigerator Condenser Fan
Slide the unit out to access the rear panel. Unplug and remove this panel to inspect the condenser fan near the compressor. Plug in briefly to check operation when the compressor activates. If the fan doesn’t respond, unplug and aim an external fan at the compressor to cool it. Test again once cooled. If the compressor runs sans fan, replace it (see below). If both components fail to start, a new relay or compressor may be needed – contact an appliance repair technician to investigate.
When to Replace Condenser Fan
Replace the condenser fan if it produces noise or fails to power on with the compressor. You may need to detach the bracket before unscrewing the fan.
Install the New Fan
Once you have the replacement condenser fan, cut the wire connections close to the old fan. Use a wire stripper to expose the ends. Attach the new fan’s wires securely with wire connectors. Conclude the repair by fastening the fan mount bracket and fan back into position.
Conclusion
If your refrigerator fails to adequately chill and freeze food, don’t despair – this guide arms you with practical troubleshooting tips to diagnose the problem and restore cooling function fast. With a bit of effort, there’s a good chance you can implement repairs yourself by replacing components like the evaporator fan.
Even if you need to call in appliance technicians, the clear step-by-step advice here will help you accurately describe issues to save precious diagnostic time and money.
