How to Fix / Troubleshooting
Safety First: Disconnect power and shut off water before working inside the ice-making compartment.
- Locate thickness sensor: In Monogram nugget and clear ice makers, the ice thickness or harvest sensor is typically mounted near the evaporator or water distribution area.
- Clean mineral deposits: Use a manufacturer-approved ice machine cleaner and a soft cloth to remove scale or mineral buildup from the sensor surfaces. Rinse thoroughly with clean water.
- Inspect wiring: Check the sensor harness for secure connections and no visible damage from rubbing or moisture.
- Run a clean cycle: After cleaning, run a full cleaning/sanitizing cycle per the Monogram user manual to ensure all sensors are free of residue.
- Replace sensor: If E6 persists, replace the ice thickness sensor / harvest sensor and reconnect harness firmly.
