Possible Causes
Ice thickness probe set too thick, Slow harvest due to scaled evaporator, Weak hot gas valve, Long freeze times from low airflow
How to Fix / Troubleshooting
Safety first: Disconnect power before adjusting probes or cleaning the evaporator.
Steps:
- Adjust thickness probe thinner: Move the ice thickness probe slightly closer to the evaporator so harvest initiates sooner, following the service manual.
- Descale evaporator: Run a full cleaning cycle with Manitowoc cleaner to remove scale that can delay harvest and cause bridging.
- Clean condenser and check fan: Improve airflow to reduce freeze time and prevent over‑freezing.
- Check hot gas valve: If harvest remains slow, have a technician test the hot gas / harvest valve for proper operation.
