Possible Causes

Incorrect thermostat calibration, Faulty temperature sensor, Oversized compressor for load, Poor ventilation around cabinet

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before accessing sensors or control boards.

Steps:

  • 1. Check installation: Ensure there is adequate clearance around the IceKing refrigerator for ventilation as per the manual. Overheating can cause short cycling.
  • 2. Verify temperature settings: Set both fridge and freezer to mid-range values and avoid frequent changes.
  • 3. Test sensors: Check fridge and freezer NTC sensors for correct resistance at known temperatures. Replace any that are out of range.
  • 4. PCB evaluation: If sensors and installation are correct, the main PCB may be miscontrolling compressor run times and should be replaced.

Note: Frequent door openings can also cause apparent short cycling; monitor usage patterns.
