Possible Causes

Defective keypad on Rayne control panel, Broken keypad ribbon cable, Control board input failure, Stuck or damaged front overlay

How to Fix / Troubleshooting

Safety first: Unplug the unit before removing the front panel.

  • 1. Try alternate method: If your model allows, attempt to start regeneration via a different button sequence or scheduled time to confirm if only the manual button is affected.
  • 2. Inspect keypad overlay: Check for physical damage, cracks, or water intrusion on the keypad. Dry the surface and avoid using harsh cleaners.
  • 3. Check ribbon cable: Remove the front panel and ensure the keypad ribbon cable is fully seated on the control board. Reseat if loose.

When to call a technician: If the keypad or control board input circuit is defective, the front panel or PCB will need replacement.
