How to Fix / Troubleshooting

Safety first: Unplug the unit before opening the control panel.

  • Inspect ribbon cable: Remove the front panel and reseat the ribbon cable connecting the keypad to the control board.
  • Check for corrosion: Look for signs of moisture damage on the keypad and board. Clean light corrosion with isopropyl alcohol and a soft brush.
