Microwave shows E08 and will not start; interior light may come on but no cooking begins.

Safety Warning: Unplug the microwave before attempting any physical adjustments to the door or latch assembly.

Steps:

• Inspect the door latch hooks on the door edge for cracks, bending, or missing plastic. If damaged, the door assembly may need replacement.
• Check that the door closes evenly and fully; adjust the microwave position so it is level and not twisted in cabinetry.
• Open and close the door firmly several times to see if E08 clears.

Advanced checks (for trained persons):

• Remove the outer cover and locate the door switch bracket on the right side.
• Verify that the bracket is secure and not bent away from the latch hooks.
• Test the door sensing switch with a multimeter for proper operation when the door is opened and closed.
• Replace the defective switch or latch bracket as needed.

If the door appears damaged or warped, replacement of the entire door assembly is often required.
