Possible Causes

Faulty touch panel or membrane keypad, Loose ribbon cable between display board and main PCB, Failed user interface board, Stuck or damaged ON/OFF button

How to Fix / Troubleshooting

Safety first: Unplug the unit before removing the control panel or display housing.

Steps to troubleshoot non-responsive controls:

  • 1. Check for lock mode: Some HOMCOM models may have a child lock or key lock. Refer to the user manual to ensure the control panel is not locked.
  • 2. Inspect the control panel: Look for cracks, moisture, or physical damage around the buttons.
  • 3. Access the interface board: Remove the top or front cover to expose the display/user interface PCB. Ensure the ribbon cable to the main board is fully seated.
  • 4. Test button operation: If you have access to service data, you can measure button contacts on the interface board with a multimeter while pressing the ON/OFF key.
  • 5. Replace the interface panel: If the keypad or touch panel is defective, install a new HOMCOM control panel or display board assembly.

Note: If the interface is good but the main board does not respond, the main PCB may need replacement.
