Top 5 Reasons Your Refrigerator is Not Cooling (and How to Fix It)

A refrigerator that has stopped cooling can lead to food spoilage. Before calling in an engineer, check these common fault points:

1. Degraded Condenser Coils

Coils located at the back or bottom of the fridge dissipate heat. If they are covered in dust or grime, heat exchange drops, causing the compressor to overheat and short-cycle. Fix: Turn off power and vacuum clean the coils.

2. Defective Start Capacitor

The compressor relies on a run/start capacitor to kickstart. If this component fails, you will hear a clicking sound every few minutes, but the compressor will not hum or start. Fix: Needs replacement using a calibrated spare of identical rating.

3. Faulty Defrost Timer / Thermostat

If frost builds up on the evaporator coils behind the freezer panel, airflow to the fresh food compartment will block. This is usually caused by a failed defrost heater, bimetal thermostat, or timer.

4. Poor Door Gasket Seal

If the magnetic rubber gasket is torn or warped, warm humid air continuously leaks in, causing ice buildup and preventing the interior from reaching the set temperature.

5. Low Refrigerant Charge

A gas leak in the capillary or evaporator coil will cause the compressor to run continuously without cooling. This requires locating the leak, sealing it, vacuuming the system, and recharging R-134a or R-600a.
