Display shows Er8; grill powers on but display is dim or unresponsive, and outputs may not function correctly.

Safety first: Unplug the grill before inspecting the power system.

• Verify outlet: Plug a known-good appliance or tester into the same outlet to confirm proper voltage. Avoid using long or undersized extension cords.
• Inspect power cord: Check the Broil King Crown Pellet power cord for cuts, burns, or crushed sections. Replace the cord if any damage is found.
• Check internal connections: Remove the controller mounting screws and gently pull the control panel out. Inspect the incoming power connectors for tightness and signs of overheating.
• Look for board damage: Examine the control board for burnt components, bulging capacitors, or discoloration near the power supply section.
• Test with another outlet: Try a different, properly grounded outlet on a separate circuit to rule out house wiring issues.
• Replace control board: If the outlet and cord are good but Er8 persists, replace the main control board with the correct Broil King Crown Pellet controller.
