Microwave displays 'door' or 'Open/Close door' and will not start even when the door is closed.

Safety: Unplug the microwave before working near the door switch assembly.

• Open and close firmly: Open the door fully and close it firmly to ensure the latches engage. Listen for distinct clicks from the switches.
• Inspect latch hooks: Look for cracked or bent plastic hooks on the door. Replace the door latch assembly if damaged.
• Check for sagging door: If the door appears misaligned or sags, hinge screws or the door itself may need adjustment or replacement.
• Door switch test (for trained users): Access the door switch bracket behind the control panel and test each microswitch with a multimeter. Replace any defective switch.

Because door switches are part of the safety system, if you are unsure, have a professional complete the repair.
