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

Stuck or misaligned door switch, Shorted light relay on control board, Wiring short in lamp circuit

Safety first: Disconnect power before accessing the door switch or control board.

Check door switch operation: Locate the plunger or reed switch near the door frame. Press it manually and listen for a click. Test continuity with a multimeter; replace if it does not change state.
Inspect switch mounting: Ensure the switch is aligned so the door fully depresses it when closed.
Control board relay: If the switch is good but the light remains on, the light relay on the control board may be stuck closed. Replace the main control board.
