Possible Causes

Failed touchpad or keypad, Loose ribbon cable, Moisture behind control panel, Faulty control board input circuit

Unplug the cooler before removing the control panel.

Dry moisture: If condensation is visible behind the panel, gently dry the area and improve room ventilation.
Reseat ribbon cable: Disconnect and reconnect the flat cable between the touch panel and main board.
Inspect for damage: Look for cracks in the touch panel or corrosion on the connector pins.
Replace panel: If specific buttons never work, replace the Luma touch control panel. If all buttons fail despite a new panel, replace the main control board.
