Smoker displays E8 and shuts down when trying to preheat or during a cook cycle.

Safety: Unplug the smoker and let it cool. High‑current connections can be hazardous if mishandled.

Inspection:

• Access the control board compartment. Identify the heater relay or solid‑state relay (often a rectangular component with heavy wires).
• Inspect for discoloration, melted plastic, or a burnt smell around the relay and its terminals.
• Tighten any loose screws or spade connectors on the relay output terminals.
• If the relay is visibly damaged or you hear no click when the smoker should be heating, the relay or entire control board likely needs replacement.
• On some models, the heater relay is separate from the main board. In that case, replace the relay module with an identical part.

Note: Relay replacement involves working near live‑voltage circuits. If you are not experienced with electrical repairs, contact a professional.
