Loose power cord at inlet, Loose spade connectors on control board, Damaged internal wiring harness, Vibration‑sensitive main board

How to Fix / Troubleshooting

Safety first: Unplug the grill before inspecting wiring.

  • Secure power cord: Ensure the cord is firmly plugged into both the grill and outlet. Avoid using loose extension cords.
  • Inspect internal connections: Remove the control panel and check all spade and plug connectors. Tighten or crimp loose terminals.
  • Check for chafed wires: Look for wires rubbing against sharp metal edges and protect with grommets or loom.
  • Test by gently tapping: With the grill running (exercise caution), gently tap the control panel area. If power cuts out, re‑inspect and secure connections or replace the main control board.
