Oven interior light stays on even when the door is closed.

Safety: Disconnect power before accessing the door switch.

• Check door closure: Ensure the door closes fully and evenly. Adjust hinges if necessary.
• Locate switch: Find the door switch plunger near the cavity opening. Press it manually to see if the light turns off (with power on, using caution).
• Replace switch: If the light never turns off or the switch feels loose or stuck, remove and replace the door switch.
• Inspect wiring: Check for shorted wires around the switch area and repair as needed.
