How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before removing the control panel.

Dry moisture: If the issue started after heavy cleaning or a spill, allow the control area to dry for several hours with power disconnected.
Reseat ribbon cable: Remove the control panel screws and gently pull the panel forward. Disconnect and reconnect the flat ribbon cable between the keypad and control board.
Test keys: Restore power and test each button. If certain keys still do not respond, the control panel/touchpad assembly is likely defective and should be replaced.
Inspect for damage: Look for cracks in the overlay or signs of wear on frequently used keys.

A non-responsive keypad cannot be repaired at the component level; replacement is the standard fix.

Control panel buttons do not respond or respond intermittently; display may still be lit.
