Gledhill unit’s display works but buttons or controls do not respond

Safety: Isolate power before removing the front control panel.

Steps:

• Power reset: Turn off power for several minutes, then restore to see if the interface recovers.
• Inspect keypad: Remove the fascia and check the ribbon cable or plug between the keypad and display PCB. Reseat connectors.
• Check for moisture: Look for signs of condensation or water ingress. Dry thoroughly and improve sealing if necessary.
• Replace keypad/display: If individual buttons or the entire keypad remain unresponsive, replace the keypad membrane or complete display module as supplied by Gledhill.

Note: Avoid using excessive cleaning fluids on the control panel, as these can penetrate and damage the keypad.
