Possible Causes

Failed start relay or overload, Weak compressor, Low line voltage, Overheated compressor due to dirty coils

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before accessing the compressor area. Components may be hot.

Steps to resolve:

  • Clean condenser coils: Dusty coils can cause overheating. Clean thoroughly with a brush and vacuum.
  • Check ventilation: Ensure adequate space around the refrigerator for heat dissipation.
  • Inspect start device: Remove the start relay/overload from the compressor (with power off). If it rattles when shaken or shows burn marks, it is likely bad.

Replacing the start device is a common repair, but if a new device does not resolve the issue, the compressor itself may be failing and will require professional replacement.
