Siemens Control or Thermostat Stuck On

Ice maker runs continuously without cycling off, ice bin overfilled or very cold

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 bin thermostat, Bin level sensor not detecting full bin, Stuck relay on control board, Incorrect temperature sensor reading

Safety: Unplug the unit before testing sensors or boards.

Stopping continuous operation:

Check bin sensor: Clean and test the bin level sensor. Replace if it does not change state when the bin is full.
Test bin thermostat: Measure continuity at different temperatures. Replace if it remains closed when it should open.
Control board: If sensors are good, the main control PCB may have a stuck relay and require replacement.
