Display shows dashes or “—” instead of temperature and smoker will not heat.

Safety first: Unplug the smoker and let it cool before removing panels.

• Locate sensor wiring: Find the cabinet temperature sensor inside the smoker and trace its wire to the control board.
• Check connections: Ensure the sensor plug is fully seated on the control board and that any in-line connectors are tight.
• Inspect for damage: Look where the sensor wire passes through the cabinet wall. If the insulation is cut or the wire is broken, replace the sensor assembly.
• Test sensor: With a multimeter, measure resistance across the sensor leads. An open circuit indicates a failed sensor that must be replaced.
• Replace control board if needed: If a known-good sensor is installed and the display still shows dashes, the control board is likely faulty.
