Possible Causes
Dirty or scaled ice thickness probe, Misadjusted thickness probe, Broken or disconnected probe wiring, Failed thickness sensor
How to Fix / Troubleshooting
Safety first: Disconnect power. Remove ice from the evaporator area where you will be working.
Steps:
- Locate thickness probe: On Manitowoc cube ice makers, the thickness probe is typically a metal or plastic probe that the ice sheet contacts before harvest.
- Clean the probe: Use Manitowoc‑approved cleaner and a soft cloth to remove scale and slime from the probe. Rinse thoroughly.
- Check adjustment: Refer to the service manual for the correct gap or position. Adjust the probe so that the ice sheet contacts it at the proper thickness.
- Inspect wiring: Ensure the probe wiring is intact and securely connected to the control board.
Replacement: If cleaning and adjustment do not restore proper operation and E16 persists, replace the ice thickness probe.
