Safety first: Disconnect power before adjusting or opening the unit.

Step 1 – Inspect door alignment: Check that the Thermador microwave door is level and flush with the cabinet. If it sags or rubs, hinges may be loose.
Step 2 – Tighten hinges: Open the door and tighten any accessible hinge screws. Do not overtighten to avoid stripping.
Step 3 – Check latch engagement: Close the door slowly and listen for distinct clicks from the interlock switches. If you do not hear them, the latch or switches may be misaligned.
Step 4 – Internal inspection (qualified persons): Remove the outer cover and inspect the latch bracket and interlock switches. Ensure the bracket is not bent and that switches are firmly mounted.
Step 5 – Replace damaged parts: Replace any broken latch bracket or faulty monitor switch with Thermador-approved components.

Note: Proper door interlock function is critical for microwave radiation safety; if unsure, use professional service.

Microwave displays E10 and will not start; sometimes after a door slam or impact.
