Caple Stuck Lamp Control or Door Switch Fault

Caple oven interior light stays on permanently, even when the door is closed and oven is off.

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 door switch, Shorted lamp relay/triac on PCB, Misaligned door latch not actuating switch, Wiring short in lamp circuit

Safety first: Isolate the oven from mains before working on the door switch or PCB.

Test door switch: Locate the door switch and test continuity with the door open and closed. Replace if it does not change state correctly.
Check latch alignment: Ensure the door catch fully depresses the switch when closed. Adjust hinges or latch if needed.
Inspect PCB: If the switch is working but the lamp remains on, the control relay or triac may be shorted. Replace the main PCB or lamp control board.
