Essick Air Keypad / Membrane Switch Failure

Digital display works but buttons do not respond or only some buttons work.

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

Worn membrane contacts, Moisture intrusion under keypad overlay, Damaged ribbon cable to control board, Cracked control panel PCB

Safety first: Unplug the humidifier before removing the control panel.

Dry the panel: If there was a spill, allow the panel to dry completely for 24 hours.
Inspect ribbon cable: Reseat the cable between the keypad and main board.
Test each button: After reassembly, plug in and test each button. If some remain unresponsive, the keypad is likely defective.
Replace keypad assembly: Order the correct Essick Air control panel or keypad and swap it, transferring any mounting hardware.
