The LG Microwave Door Interlock Micro Switch (Part Number / SKU: 6600JB3001E) is an authentic OEM replacement switch designed for compatible LG microwave ovens. Mounted inside the door latch assembly, this snap-action electrical switch communicates door status (open or closed) to the main control board and power relays. Over time, electrical arcing or mechanical wear on the spring-loaded actuator arm can cause switch failure, resulting in error codes, a dead unit, or a microwave that refuses to start when closed. This genuine OEM replacement restores proper safety interlocking.
