Smoker temperature fluctuates widely during cooking, causing inconsistent results.

Safety first: Unplug before accessing internal wiring.

• Minimize door opening: Avoid opening the door frequently; each opening dumps heat and confuses the controller.
• Shield from wind: Move the smoker to a more sheltered location away from strong drafts.
• Check sensor wiring: Tighten the sensor connector at the control board and inspect for intermittent breaks.
• Monitor with external probe: Use a separate probe thermometer to verify if fluctuations are real or just display anomalies. Replace the sensor or control board if readings are erratic.
