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 relay on control board, shorted lamp circuit, faulty door switch, incorrect wiring after repair

Safety first: Isolate the oven from mains before inspection.

Door switch test: If your model has a visible door switch, press it manually and see if the light goes off. Replace the switch if it fails.
Control reset: Power cycle the oven to see if the relay releases.
PCB inspection: Check the control board for a welded light relay; replace the board if necessary.
