Display shows E8; smoker runs but temperature is unstable and swings widely.

Safety first: Unplug the smoker before accessing sensors or wiring.

• Locate auxiliary sensor: Some GE electric smokers use a second sensor near the air intake or exhaust. Refer to your model diagram and locate this probe.
• Inspect for damage: Check the sensor body and wiring for kinks, cuts, or pinch points, especially around the door and cabinet seams.
• Check connections: Trace the harness back to the control board and ensure the connector is fully seated and free of corrosion.
• Test sensor: Disconnect the sensor and measure resistance at room temperature. Compare to the service specifications. A reading far outside the expected range indicates a failed sensor.
• Secure harness: Use high-temperature cable ties to keep the harness away from hot surfaces and moving parts.
