Possible Causes

Worn conductive traces in membrane keypad, Moisture ingress from steam, Loose keypad ribbon cable, Faulty control PCB key-scan circuit

How to Fix / Troubleshooting

Steps:

  • Dry out: If the microwave is above a stove, unplug it and allow it to dry for several hours to a day to see if responsiveness improves.
  • Clean surface: Wipe the keypad surface with a slightly damp cloth and then dry thoroughly.
  • Test all keys: Note which keys fail; widespread failure usually indicates a bad membrane keypad.
  • Inspect ribbon cable (technician): Remove the control panel (unplugged) and reseat the keypad ribbon cable on the control PCB.
  • Replace keypad: If issues persist, replace the membrane keypad assembly compatible with your Clatronic model.
