Safety first: Disconnect power before removing the door switch.

Observe light behavior: Open and close the door and watch the interior light. Flickering or delayed operation indicates a switch issue.
Check switch alignment: Ensure the door fully depresses the switch plunger when closed.
Replace switch: Remove the switch from the cabinet and install a new Liebherr door switch if operation is inconsistent.
Test ice maker: After replacement, monitor ice production over several days to confirm stability.
