Possible Causes

Defective start relay/PTC, Weak compressor motor, Overheating overload protector, Low voltage supply

How to Fix / Troubleshooting

Safety: Unplug the refrigerator before handling the compressor or electrical components.

Steps:

  • 1. Verify voltage: Ensure the outlet provides correct voltage and is not shared with heavy loads causing drops.
  • 2. Inspect start relay: Remove the start relay/PTC from the compressor. If it rattles or shows burn marks, replace it with a compatible compressor start relay/PTC.
  • 3. Check overload protector: Test the overload for continuity when cool. Replace if open.
  • 4. Test compressor windings: Measure resistance between compressor terminals. If windings are open or shorted, the compressor is faulty.

When to call a technician: If a new relay does not solve the problem or if the compressor windings are defective, professional sealed system service is required.
