Digital Bradley smoker will not heat; display shows E1 shortly after power‑up.

Safety first: Unplug the smoker from the mains before removing panels or touching wiring. Allow the cabinet to cool completely.

Steps to troubleshoot E1:

• Check sensor plug at back wall: On most Bradley digital smokers, the temperature sensor (RTD probe) is mounted inside the cabinet near the top rear and connects through a small plug on the back wall. Make sure this plug is fully seated and not bent or corroded.
• Inspect sensor cable: Follow the sensor wires from the inside probe to the rear connector. Look for cuts, melted insulation, or broken conductors. If damaged, the sensor assembly should be replaced.
• Clean and reseat connectors: Lightly clean any oxidation on the rear sensor plug and the mating connector from the control box using electrical contact cleaner. Reseat firmly.
• Check continuity (advanced): With the smoker unplugged, remove the control box and disconnect the sensor leads from the board. Use a multimeter to verify the sensor has continuity and a resistance value that changes with temperature. An open circuit indicates a failed sensor.
• Replace the RTD sensor: If the sensor is open or physically damaged, install a new Bradley temperature sensor probe, routing the wire away from hot surfaces and sharp edges.

If E1 persists after sensor replacement, the fault may be on the control board and a qualified technician or Bradley support should be consulted.
