The smoker displays E08 and shuts down heating; this may occur when using very high temperatures or during long cooks.

Safety first: Allow the smoker to cool completely before moving or inspecting.

• Relocate the smoker: Ensure it is used outdoors or in a well-ventilated area, not inside cabinets or tight alcoves. Maintain clearances recommended in the manual.
• Check vents: Inspect all intake and exhaust vents for grease, foil, or debris. Clean thoroughly to restore airflow.
• Inspect ambient sensor (if equipped): Some models have a separate ambient or cabinet sensor near the control area. Check its wiring and cleanliness; replace if damaged.
• High-limit thermostat: If the high-limit thermostat is weak, it may trip prematurely. Test continuity when cool and compare to specifications; replace if out of specification.
• Test at lower settings: Run the smoker at a moderate temperature. If E08 no longer appears, overheating due to environment or airflow was likely the cause. Persistent E08 suggests sensor or control board issues.
