How to Fix / Troubleshooting
Safety first: Unplug the unit and let it cool if it feels hot.
Steps to improve reliability:
- Improve cooling and ventilation: Clean vents and coils, ensure adequate clearance, and operate in a cooler room.
- Reset unit: After cooling for 30 minutes, plug back in and restart. Observe how many cycles it completes before stopping.
- Check sensors: Clean and inspect the ice full sensor and temperature sensors for proper placement.
- Stable power: Avoid using long extension cords or power strips. Plug directly into a wall outlet.
- Board replacement: If the unit consistently locks up after a few cycles, the main control board may be failing and should be replaced.
