Possible Causes
Failed door switch, Misaligned door latch, Faulty START button on keypad, Defective main control board relay
How to Fix / Troubleshooting
Safety first: Unplug the Café microwave before inspecting the door.
Steps to try:
- Confirm door closure: Open and close the door firmly. The unit will not start unless all door switches indicate closed.
- Try different keys: See if other keys respond normally (clock, timer). If START alone is unresponsive, the keypad may be failing.
- Listen for relay click: When pressing START, listen for a faint click from inside. No click may indicate a control board issue.
- Service: A technician should test the door switches and START key function, and replace the door switch assembly, keypad, or main control board as needed.
