How to Fix / Troubleshooting

Safety first: Immediately turn OFF and unplug the grill. Do not continue operating until the source is identified.

Steps:

  • Visual inspection: Remove the control panel and service covers. Look for discolored, melted, or charred wires and connectors.
  • Check terminal tightness: Gently tug on spade connectors and screws at the control board. Tighten any loose connections.
  • Isolate damaged parts: Replace any burnt connectors or wiring harness sections with Napoleon-approved parts.
  • Board inspection: If the control board shows burn marks or bulging components, it must be replaced.

Do not operate the grill until all damaged components are replaced and wiring is secure.
