Thermador Microwave door not opening/closing properly
If your Thermador microwave door won't open or close properly, the open lever is the most likely cause. Inspect it for cracks or damage and replace it if it no longer releases the door. Next, check the door spring, door latch, and plastic door hook. A broken door hook may fail to engage the latch or release correctly, leaving the microwave door stuck or preventing it from closing securely. If those parts are intact, inspect the button spring inside the door open button, then test the button for a broken internal component. These parts can cause a Thermador microwave door latch problem, microwave door won't open, or microwave door won't close symptom. Enter your model number to find the exact replacement open lever, door spring, latch, hook, button spring, or door button for your specific microwave. Most repairs involve the door assembly, but if you must remove the outer cabinet, unplug the microwave first and use caution: the high-voltage capacitor can store a lethal charge even after power is disconnected. The capacitor must be properly discharged before any interior work, and this repair may require a qualified technician if you are not familiar with capacitor discharge procedures.

04 - Thermador Microwave Door Hook
The door hook engages with the door latch to keep the door closed during operation. Since the door hook is made of plastic, it can break due to regular wear. If the door hook is broken, it won’t release the door properly, preventing the door from opening. If the door hook is broken, replace it.
