Possible Causes
Low refrigerant charge, weak compressor, evaporator thermistor out of calibration, dirty condenser causing high head pressure
How to Fix / Troubleshooting
Warning: Refrigeration system work (refrigerant, compressor) must be done by an EPA-certified technician. Homeowners should limit work to cleaning and basic checks.
- Clean condenser: Unplug the unit and thoroughly clean the condenser coil to improve heat rejection.
- Check ambient temperature: Ensure the ice maker is installed in a room within the specified temperature range (typically 55–110°F).
- Inspect evaporator plate: Remove the front panel and observe the freeze cycle. The evaporator plate should frost evenly. Heavy frost on only part of the plate suggests a sealed system issue.
- Test thermistor: Measure the evaporator thermistor resistance and compare to the tech sheet. Replace if out of spec.
- Call a technician: If cleaning and sensor replacement do not correct the issue, contact a qualified technician to check refrigerant charge and compressor performance.
