How to Fix / Troubleshooting

Safety first: Unplug the microwave before removing the control panel.

Step-by-step checks:

  • 1. Test all keys: Note which keys fail. If entire rows or columns are dead, the ribbon or board may be at fault.
  • 2. Dry and clean: If the panel was exposed to steam or cleaning fluids, allow it to dry completely and gently wipe the surface.
  • 3. Reseat ribbon cable: Remove the control panel and carefully unplug/replug the keypad ribbon cable into the control board.
  • 4. Replace keypad: If specific keys remain unresponsive, replace the membrane keypad or full control panel assembly as supplied by Paderno.
