Smoker shuts off mid-cook and will not restart until cooled down.

Safety first: Allow the smoker to cool fully before troubleshooting.

• Improve clearance: Move the smoker at least several inches away from walls or other objects to allow proper airflow.
• Check exhaust vent: Ensure the vent is open and not covered with foil or grease. Clean any buildup.
• Inspect high-limit thermostat: If it trips frequently at normal cooking temperatures, it may be weak. Replace the high-limit thermostat.
• Verify ambient conditions: Avoid operating in direct sun on very hot days, which can raise cabinet temperature beyond design limits.
