Digital Old Smokey electric smoker will not heat; display powers on but shows E1 and the heating element never gets hot.

Safety first: Unplug the smoker from the outlet and allow it to cool completely before opening any panels.

Steps to check the temperature sensor circuit:

• 1. Locate the temperature sensor: On most Old Smokey electric smokers with digital controls, the temperature sensor (thermistor or probe) is mounted inside the cooking chamber, usually on the back wall or near the top, with two wires leading through the cabinet to the control board.
• 2. Inspect the sensor and wiring: Look for broken insulation, burnt spots, or a sensor that is physically damaged or bent. Check where the sensor wires pass through the cabinet for pinching or cuts.
• 3. Check connections at the control board: Remove the control panel or rear access cover (depending on model). Find the two-wire connector from the temperature sensor to the control board. Reseat the connector several times to clear oxidation and ensure a tight fit.
• 4. Test the sensor with a multimeter: With the smoker unplugged, disconnect the sensor from the board. Measure resistance across the two sensor leads. A typical thermistor will show several kilo-ohms at room temperature. If the meter reads OL (open) or 0 Ω (short), the sensor is defective.
• 5. Inspect for corrosion: If the sensor terminals or connector pins are green, white, or crusty, clean them gently with contact cleaner and a small brush, then reconnect.
• 6. Replace the sensor if open: If the sensor is open or physically damaged, replace it with an OEM Old Smokey temperature sensor/thermistor assembly. Route the new wires along the original path and secure them away from the heating element.
• 7. Power up and test: Reassemble all covers, plug the smoker back in, and set a low temperature. Confirm that the E1 code clears and the element begins to heat.

When to call a technician: If the sensor tests good but E1 persists, the fault may be on the control board sensor input circuit, which usually requires board-level replacement or professional diagnosis.
