EdgeStar Short Cycling – Overheat or Sensor Misread

EdgeStar ice maker cycles on and off frequently without completing a full ice-making cycle.

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

Overheating due to poor ventilation, Faulty temperature sensor, Control board logic fault

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

Improve airflow: Ensure proper clearance around the unit and clean condenser coils and fan.
Check ambient temperature: Extremely hot environments can cause protective shutdowns. Move the unit to a cooler location if possible.
Inspect thermistors: Verify evaporator and bin thermistors are properly mounted and wiring is intact.
Control board replacement: If sensors test good and airflow is adequate, the main control board may be misreading inputs and require replacement.
