Oven door will not close fully; heat escapes and cooking is uneven.

Safety first: Ensure the oven is cool before working on the door.

• Inspect hinges: Open the door and check for sagging or play in the hinges. Tighten mounting screws on the door and cabinet side.
• Check for obstructions: Make sure racks or trays are not preventing the door from closing.
• Examine gasket: Look for twisted or torn gasket material that could hold the door open.

If hinges are worn or bent, replace both door hinges as a set for proper alignment.
