Possible Causes
Worn membrane contacts, Stuck button due to spilled liquid, Failed tact switch on PCB, Cracked control panel overlay
How to Fix / Troubleshooting
Safety first: Unplug before working on the panel.
- Clean surface: Wipe the control panel with a slightly damp cloth and mild detergent, then dry. Do not allow liquid to seep into the edges.
- Check for stuck keys: Press each button individually to feel for sticking. If stuck, gently work the button to free it.
- Open panel: Remove the panel and inspect the keypad membrane and tact switches. Look for corrosion or physical damage.
- Replace worn parts: Replace the keypad membrane or individual tact switches if they no longer click or register.
Persistent unresponsiveness across multiple keys usually requires replacing the entire keypad/control panel assembly.
