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.
