Refrigerator Runs Constantly

Compressor never stops running, high energy bills

About This Problem

While refrigerators cycle on and off normally, a unit that runs constantly indicates a problem. This wastes energy and can shorten compressor life.

Possible Causes

  • Dirty condenser coils forcing compressor to work harder
  • Damaged or worn door seals
  • Thermostat set too cold
  • Warm ambient temperature or poor ventilation
  • Defrost timer or heater problems
  • Low refrigerant level
  • Failing compressor

Things to Try First

  1. 1Clean condenser coils (located underneath or behind the unit)
  2. 2Check and clean door seals, ensure proper closure
  3. 3Adjust thermostat to recommended settings (37°F for fridge, 0°F for freezer)
  4. 4Ensure adequate space around the unit for ventilation
  5. 5Don't place hot food directly in the refrigerator
  6. 6Minimize door opening frequency

When to Call a Professional

Contact a certified technician if you experience any of the following:

  • Unit still runs constantly after cleaning coils and checking seals
  • Interior temperatures are not reaching proper levels
  • Compressor is unusually hot to the touch
  • You hear unusual sounds from the unit
