SMEG Short Cycling Due to Sensor or Control Issues

Ice maker cycles on and off frequently without producing much ice.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty temperature sensor, Ice level sensor misreading, Control board logic fault, Overheating from poor ventilation

Safety first: Unplug the unit before testing sensors or boards.

Steps:

Check ventilation and condenser: Clean condenser coils and ensure adequate airflow to prevent overheating shutdowns.
Test sensors: Verify cabinet and evaporator sensor resistances against SMEG specs. Replace any that are out of range.
Inspect ice level sensor: Clean and test the sensor to ensure it does not falsely signal a full bin.
Control board: If all sensors are correct and cycling persists, the main PCB may be defective and require replacement.
