Jacuzzi pool heater responds slowly or not at all to button presses on the control panel.

Safety first: Turn off power before removing the control panel.

Steps to restore keypad function:

• Clean panel surface: Wipe the keypad with a dry cloth to remove dirt and moisture. Do not use solvents.
• Inspect ribbon cable: Reseat the cable between the keypad and main board.
• Test specific buttons: If only certain buttons fail, the membrane keypad is likely worn and should be replaced.
• Replace keypad/display: Install a Jacuzzi-compatible display/keypad assembly if cleaning and reseating do not help.
