Grundig Ice Level Detection Failure

Ice maker runs continuously and does not stop making ice, bin overfills

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

Blocked or failed ice level sensor, Disconnected sensor harness, Stuck mechanical shutoff arm, Faulty main control board input

Safety first: Unplug the unit to stop ice production and prevent overflow.

Steps to check:

Clean sensor: Wipe the optical ice level sensor or mechanical arm to remove frost and debris.
Check movement: Ensure any mechanical shutoff arm moves freely and is not jammed by ice or the bin.
Inspect wiring: Verify the sensor harness is connected firmly to the control board.
Test operation: Restore power with the bin full. If the unit continues to make ice despite a full bin and a known-good sensor, the control board may be defective.
