Refrigerator Not Cooling Properly? Top Causes & Easy Checks

Coming home to melted ice cream or spoiled milk is frustrating. A refrigerator that has stopped cooling effectively is usually caused by easily repairable issues.

Quick Diagnostic Checklist:

• Dusty Condenser Coils: Thick dust buildup on rear or bottom coils prevents heat dispersion. Vacuum them every 6 months.
• Worn Door Gasket Seal: Place a paper note between the door seal and close it. If it pulls out easily with no resistance, warm ambient air is leaking in.
• Faulty Defrost Timer / Bi-Metal Sensor: In frost-free fridges, frost blocks the air passages between freezer and refrigerator compartments.
• Compressor Relay / Capacitor Failure: If you hear clicking sounds every few minutes without the hum of the compressor, the start relay may need replacement.
