Possible Causes
Failed compressor feedback sensor (if equipped), Control board not detecting compressor off state, Stuck compressor relay, Low refrigerant causing long run times
How to Fix / Troubleshooting
Safety: Unplug the unit before working on electrical components.
- Check ambient conditions: Ensure the cooler is not installed in a very hot room or enclosed cabinet, which can cause long compressor run times.
- Door seal: Verify the door gasket is sealing properly and the door is not frequently opened.
- Control board inspection: If CF persists under normal conditions, inspect the main control PCB for a stuck relay or burnt components. Replace the board if necessary.
- Sealed system check: If the compressor runs constantly but cooling is weak, a sealed system issue (refrigerant leak or restriction) may exist and requires a professional technician.
