Zodiac pool heater display is on but does not respond to button presses.

Safety: Turn off power before removing the control panel.

• Visual inspection: Look for cracks, bubbling, or discoloration on the keypad overlay that indicate water intrusion or wear.
• Dry moisture: If condensation is visible, allow the panel to dry thoroughly and correct any gasket or cover issues that allowed water in.
• Check ribbon cable: Reseat the cable between the keypad and control board. Inspect for kinks or broken traces.
• Test individual buttons: After restoring power, test each button. If none respond, the keypad or display board is likely failed.
• Replace keypad/display: Install a new Zodiac keypad or display assembly as specified for your model.
