Microwave shows E08 and stops mid-cycle; interior light and fan shut off abruptly.

Safety first: Unplug the microwave before any internal inspection.

Steps:

• 1. Check door fit: Close the door and gently push on each corner. It should feel solid with no wobble. If pressing on the door allows the unit to run without error, the latch or switches are misaligned.
• 2. Inspect latch area: Look for cracked or worn door latch hooks. Clean any food residue that may prevent full closure.
• 3. Test operation: Start a short cook cycle and lightly tap the door. If the unit stops and E08 appears, the door switch circuit is unstable.
• 4. Internal check (experienced DIYers): Remove the cabinet and locate the door switch assembly. Verify that all switches are firmly mounted and that the actuator levers move fully when the door is closed.
• 5. Tighten and adjust: Tighten any loose mounting screws on the latch bracket. Replace any switch that shows signs of arcing or discoloration.

Note: Proper door alignment is critical for microwave safety; if the door or hinges are bent, seek professional service.
