De'Longhi Keypad / Control Panel Failure

De'Longhi portable AC shows correct display but buttons on the control panel do not respond.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck or damaged membrane keypad, Loose ribbon cable to main PCB, Liquid spill into control panel, Faulty control PCB

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

1. Try remote: If the remote still controls the unit, the issue is likely with the panel keypad, not the main PCB.
2. Inspect keypad cable: Remove the top cover and check the flat ribbon cable from the keypad to the PCB. Reseat the connector.
3. Check for moisture: Look for signs of liquid spills or corrosion on the keypad board. Dry and clean gently if minor.
4. Replace keypad: If specific buttons never work or feel stuck, replace the control panel keypad assembly.
