Display shows DOOR or similar and oven will not start a self-clean or high-heat cycle.

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

Steps to try:

• Check closure: Close the door firmly and verify that it is even with the front of the range and not sagging.
• Inspect hinges: Look for bent or loose hinges. Tighten hinge screws at the door and frame.
• Test door switch: Locate the door switch plunger (usually in the frame). Press it manually and listen for a click. If the oven light does not respond or no click is heard, the switch may be faulty.
• Replace switch: With power off, remove the switch from the frame and install a new BlueStar-compatible door switch.

When to stop: If the door is warped or the frame is damaged, professional adjustment or replacement may be required.
