Lg Range LRG3091SB Doesn't shut off

This switch assembly is the door lock mechanism for select front-load washers. It detects when the door is closed and locks it during operation, allowing the washer to start and run safely without interruptions.

• Monitors door position and signals the control; failure can prevent the cycle from starting or trigger door/lock errors
• Engages the latch to secure the door during wash and spin; a bad lock may stop the cycle mid-wash
• Coordinates door unlock at cycle end; faults can delay or prevent unlocking
• Intermittent operation may cause sporadic starts or pauses

• Disconnect power and turn off water supply before servicing
• Access the lock behind the front panel at the door opening; remove the door boot clamp to reach the mounting screws
• Move wire connectors to the new assembly one at a time to maintain placement
• Reassemble and verify proper locking and unlocking before running a full cycle
