Interior light stays on even when the door is closed, causing warming inside.

Safety first: Unplug the unit before working on the door switch or light circuit.

• Door closure check: Verify the door is fully closing and the gasket is sealing. Adjust leveling if needed.
• Door switch test: Locate the door switch or magnetic sensor. With the door open, manually actuate the switch or hold a magnet near the frame and see if the light turns off.
• Replace switch/magnet: If the light does not respond, replace the door switch or magnet assembly.
• Control board: If a new switch does not fix the issue, the control board may be stuck driving the light on and may need replacement.
