How to Fix / Troubleshooting

Safety first: Unplug the microwave before attempting mechanical repairs.

Step-by-step checks:

1. Allow cooling: Let the microwave cool for several minutes; slight sticking can occur due to pressure differences.
2. Inspect release button: Press the door release button and feel for normal resistance. If it feels loose or jammed, the internal lever may be broken.
3. Access latch mechanism: Remove the control panel to access the door latch and release lever assembly.
4. Check for broken parts: Look for cracked plastic levers or springs out of place. Replace damaged components with Grundig-compatible parts.

After repair, verify that the door opens and closes smoothly and that the interlock switches operate correctly.

Microwave door will not open or is very hard to open after cooking.
