How to Fix / Troubleshooting
Safety first: Turn off power before removing the front panel or keypad assembly.
- Inspect keypad: Look for cracks, UV damage, or water behind the display window. Dry any moisture and improve sealing if needed.
- Check ribbon cable: Ensure the cable between the keypad/display and main board is fully seated and not damaged.
- Test buttons: With power restored, test each button. If some or all are unresponsive, the keypad assembly likely needs replacement.
- Replace UI: Install a new Raypak keypad/display assembly, ensuring gaskets are properly seated to prevent future water ingress.
