Smoker temperature fluctuates widely; swings 40–60°F above and below set point.

Safety first: Unplug the smoker before accessing wiring.

• Secure sensor connections: Remove the control panel and firmly reseat the temperature sensor connector on the board.
• Inspect door gasket and latch: Replace worn gaskets and adjust the latch so the door closes tightly.
• Improve placement: Move the smoker to a sheltered location out of direct wind. Avoid placing it where gusts can enter the vent directly.
• Monitor relay operation: During a test run, listen for rapid or erratic clicking from the control board relay. If it chatters or sticks, replace the control board.
