Furnace display is on but does not respond to button presses or changes settings erratically.

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

Faulty display/keypad module, Moisture ingress, Damaged ribbon cable, Control board communication fault

Safety: Turn off power before removing the front panel.

Dry the panel: If condensation is visible, gently dry the display area and ensure the room is not excessively humid.
Check ribbon cable: Reseat the cable between the display module and the main PCB.
Power cycle: Restore power and test button response.

If the issue persists, the display/keypad module likely needs replacement by a Kospel service technician.
