Possible Causes

Failed compressor start relay, Open overload protector, Locked rotor in compressor, Low line voltage

How to Fix / Troubleshooting

Safety: Unplug the unit before touching the compressor or electrical components. The compressor shell can be very hot.

Steps:

  • Verify voltage: Ensure the outlet provides correct voltage (typically 115–120V AC). Low voltage can prevent starting.
  • Inspect relay/overload: Remove the cover on the side of the compressor to access the start relay and overload. Look for burn marks or melted plastic.
  • Test and replace: If the relay rattles when shaken or shows signs of overheating, replace the relay/overload assembly with a Whynter-compatible kit.
  • Monitor operation: After replacement, restore power and observe. If the compressor still fails to start and continues clicking, the compressor may be mechanically locked.

Note: A locked compressor requires replacement by a licensed refrigeration technician; it is not a DIY repair.
