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

Safety first: Turn off power at the breaker before accessing the door switch or control panel.

Steps to check and correct:

• Check door closure: Ensure the door closes fully and evenly. If it sags, adjust or tighten hinges.
• Locate door switch: The switch is usually located in the front frame of the oven, activated by the door. Press it manually to see if the light goes off (with power on briefly for testing).
• Inspect and test switch: With power off, remove the switch and test for continuity. It should be open when not pressed and closed when pressed. Replace if it remains closed.
• Check wiring: Inspect wiring to the switch and light for shorts or melted insulation.

When to call a technician: If the switch tests good but the light remains on, the control board may be stuck driving the light circuit and should be checked by a technician.
