A healthy refrigerator cycles the compressor on and off throughout the day. If yours seems to run nonstop, it's fighting to hold its temperature — here's what's usually behind that.
Dirty Condenser Coils
Coils buried in dust can't release heat efficiently, so the compressor keeps running to make up the difference.
Fix: Vacuum the coils underneath or behind the unit every six to twelve months — more often in a humid climate.
Worn Door Gasket
A gasket that's lost its seal lets warm air leak in around the clock.
Fix: Run the dollar-bill test — if it pulls out with no resistance, replace the gasket.
Faulty Defrost System
Frost building up on the evaporator chokes off airflow, so the compressor runs at full tilt without actually cooling well.
Fix: A technician can confirm whether the defrost heater or thermostat has failed.
