Timer counts down but heating stops before the timer reaches zero.

Safety first: Unplug the smoker before inspecting internal components.

• Monitor temperature: Use an independent oven thermometer to verify actual cabinet temperature when the heater shuts off.
• Check vents and airflow: Ensure exhaust and intake vents are not blocked, which can cause localized overheating.
• Inspect high-limit thermostat: If it is cycling open prematurely due to poor contact with the cabinet or age, replace it.
• Secure wiring: Check for loose connections at the power cord terminal block and control board that could cause intermittent power loss.
