How to Fix / Troubleshooting
Safety first: Disconnect power before inspecting internal components.
Steps:
- Check ventilation: Ensure the Manitowoc unit has the required clearances and that air inlets and outlets are not blocked.
- Clean condenser: Dirty coils can cause overheating and safety shutdowns. Clean thoroughly.
- Inspect sensors: Check temperature and safety sensors for secure mounting and wiring. Replace any obviously damaged sensors.
- Check power connections: Tighten loose connections at the terminal block and control board.
