Possible Causes
Faulty harvest heater (if equipped), incorrect hot gas valve operation, misreading evaporator sensor, scale buildup preventing release
How to Fix / Troubleshooting
Safety: Unplug the unit before defrosting or working near the evaporator.
Steps:
- Manual defrost: Turn off and unplug the ice maker. Allow all ice and frost to melt naturally or use a bowl of warm water placed inside (do not use sharp tools or hair dryers).
- Clean evaporator: Remove mineral scale with a soft cloth and vinegar solution, then rinse.
- Check sensor placement: Ensure the evaporator sensor is firmly attached to the plate so it can detect temperature correctly.
- Test operation: After reassembly, run a cycle and observe whether ice releases cleanly. If not, a technician may need to check the hot gas valve or harvest heater circuit.
