Refrigerator Not Cooling? Troubleshooting Guide for Homeowners
Step-by-step guide to diagnosing why your refrigerator stopped cooling. Simple fixes to try before calling for repair.
A refrigerator that stops cooling puts your food at risk. Before calling for repair, try these troubleshooting steps -- some common problems have simple solutions.
Check the Thermostat Setting
Someone may have accidentally bumped the temperature dial or a child pressed buttons on the display. Verify the thermostat is set to the recommended 35-38 degrees for the refrigerator compartment.
Check the Condenser Coils
Condenser coils on the back or bottom of the refrigerator dissipate heat. When covered in dust and pet hair, they can not do their job effectively. Pull the refrigerator out and vacuum the coils with a brush attachment. This simple step resolves many cooling problems and should be done every 6-12 months.
Check the Vents
Cold air flows from the freezer to the refrigerator through internal vents. If food items are blocking these vents, airflow is restricted and the refrigerator section warms up. Rearrange items so vents are clear.
Check the Door Seals
Close the door on a dollar bill. If the bill slides out easily, the gasket is not sealing properly and warm air is leaking in. Replace worn or damaged door gaskets.
Listen to the Compressor
Is the compressor running? You should hear a low humming from the back or bottom. If it is silent, the compressor, start relay, or overload protector may have failed. If it is running but the refrigerator is not cooling, the condenser fan, evaporator fan, or defrost system may be at fault.
When to Call a Professional
If the basic checks above do not resolve the issue, or if you hear clicking sounds from the compressor area, notice ice buildup inside the freezer walls, or find water pooling on the floor, it is time for professional diagnosis. PCG Climate provides same-day refrigerator repair across the East Bay.
