Smoker overheats or shuts down; display shows E2 during operation.

Safety first: Unplug the smoker and let it cool fully. Do not operate if it is overheating.

• Inspect sensor and wiring: Locate the cabinet temperature sensor inside the smoker. Check if the sensor or its wiring is touching the heating element or metal surfaces that could have melted the insulation. Look for melted or fused wires.
• Check for moisture: Open the control housing and inspect the sensor connector on the control board. If there is condensation or grease, dry the area thoroughly and clean with electrical contact cleaner.
• Measure resistance: Disconnect the sensor and measure its resistance at room temperature. Compare to the expected value in the service manual (typically a few kΩ). A near-zero reading indicates a shorted sensor that must be replaced.
• Secure routing: Reroute the sensor harness away from the heating element and sharp edges. Use high-temperature cable ties if needed.
• Test operation: Reassemble, plug in, and run the smoker on a low setting while monitoring temperature. If E2 returns, replace the sensor assembly.
