Refrigerator runs constantly
What can I do?
If a refrigerator runs constantly without cycling off, it could indicate an issue. Here are some common causes and solutions
1. Dirty Condenser Coils
Issue: Dust and debris prevent proper heat dissipation, making the compressor work harder. Fix:Clean the condenser coils (usually located at the back or bottom) with a vacuum or coil brush.
2. Faulty Door Gasket
Issue: A damaged or loose gasket lets warm air in, causing the fridge to overwork.
Fix: Inspect the gasket for cracks or gaps and replace if needed. Ensure the door closes tightly.
3. Refrigerant Leak
Issue: Low refrigerant levels force the compressor to run continuously.
Fix: A professional technician should check for leaks and recharge the system if necessary.
4. Malfunctioning Thermostat
Issue: If the thermostat fails, it may not signal the compressor to turn off.
Fix: Test with a multimeter and replace if faulty.
5. Blocked or Frozen Evaporator Coils
Issue: Ice buildup restricts airflow, causing the fridge to work harder.
Fix: Defrost the unit and check for a faulty defrost system (heater, timer, or sensor).
6. Faulty Temperature Sensor (Thermistor)
Issue: A bad sensor can send incorrect temperature readings to the control board.
Fix: Use a multimeter to check resistance; replace if defective.
7. Overloaded or Poorly Ventilated Fridge
Issue: Blocking air vents or overloading the fridge can cause cooling inefficiency.
Fix: Arrange food properly and ensure vents are clear for proper airflow.
8. Defective Control Board or Relay
Issue: A failing control board may not regulate the compressor properly.
Fix: Inspect for burnt components and consider replacing if necessary.
