Smoker heats but cannot reach set temperature; stalls 30–50°F below target.

Safety first: Use heat-resistant gloves when checking for leaks around a hot smoker.

• Check door seal: With the smoker running, carefully feel around the door perimeter for hot air leaks. Inspect the silicone gasket for cracks, flattening, or gaps. Replace if damaged.
• Inspect element: Look for areas of the element that do not glow or heat evenly. A partially failed element can reduce output and should be replaced.
• Shield from wind: Move the smoker to a sheltered location away from strong wind and extreme cold. Avoid operating below the minimum ambient temperature specified in the manual.
• Verify load: Avoid overloading the racks with dense, cold food which can absorb heat faster than the element can supply it. Preheat the smoker before loading.
• Sensor check: Compare the smoker's displayed temperature with a reliable oven thermometer placed near the center rack. If readings differ greatly, the cabinet sensor may be out of calibration and require replacement.
