Worn or damaged keypad membrane, loose ribbon cable to PCB, liquid spill on control panel, failed control PCB input circuit
How to Fix / Troubleshooting
Safety: Disconnect power before removing the control panel.
Steps:
- Check remote: Verify that the unit responds normally to the remote control; if so, the issue is likely with the panel buttons.
- Inspect panel: Remove the front cover and inspect the keypad area for signs of moisture or corrosion.
- Ribbon cable: Reseat the ribbon cable connecting the keypad to the PCB.
- Dry and clean: If there was a spill, gently dry the area and clean with isopropyl alcohol.
- Replace panel or PCB: If buttons still do not work, replace the keypad assembly or main PCB as required.
