Possible Causes

Worn membrane keypad, Moisture intrusion, Cracked control panel, Loose keypad ribbon cable

How to Fix / Troubleshooting

Safety first: Unplug the microwave before working on the control panel.

  • Dry and clean: If the panel has been exposed to steam or spills, let it dry for several hours unplugged. Wipe gently with a dry cloth.
  • Test all keys: Note which keys fail. If failures are in a pattern (e.g., a row or column), the keypad matrix is likely damaged.
  • Reseat ribbon cable: Remove the control panel and reseat the keypad ribbon into the control board.
  • Replace keypad: If issues persist, replace the membrane keypad or entire control panel assembly with an Oster-compatible part.
