How to Fix / Troubleshooting

Safety first: Turn OFF generator, open main breaker, and disconnect battery before opening the control panel.

  • Check power to board: Verify battery voltage at the control board input terminals.
  • Inspect for moisture: Look for signs of water, corrosion, or insect nests inside the control compartment. Dry thoroughly and correct any enclosure leaks.
  • Check fuses: Test all low-voltage fuses on the control board and replace any blown fuses with identical ratings.

When to call a technician: If the board remains unresponsive, it likely requires replacement and reprogramming by a Centurion-authorized technician.
