How to Fix / Troubleshooting

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

Step-by-step checks:

  • 1. Test all keys: Identify whether only certain keys or the entire keypad is affected.
  • 2. Dry the panel: If moisture is suspected, allow the unit to dry for several hours with good ventilation.
  • 3. Reseat ribbon cable: Remove the control panel and reseat the keypad ribbon cable on the control PCB.
  • 4. Replace keypad: If specific keys remain unresponsive, replace the membrane keypad or complete control panel assembly with a Daewoo-compatible part.
