Display shows "door" or a door icon; oven will not start a cooking cycle.

Safety first: Ensure the oven is cool before adjusting the door or hinges.

Step-by-step checks:

• Verify closure: Close the door firmly and check that it sits flush with the cabinet on all sides.
• Inspect hinges: Look for sagging or bent hinges that prevent the door from fully engaging the latch.
• Check gasket: Inspect the door gasket for tears, bulges, or debris that could keep the door from sealing.
• Test door switch: Locate the door switch and listen for a distinct click when the door closes. If accessible, test continuity with a multimeter.

When to replace parts: Replace the door switch if it does not change state when the door closes. Replace door hinges or door gasket if they are damaged or misaligned.
