Old Smokey
Erratic Temperature Control / Sensor Placement Issue
Old Smokey electric smoker cycles on and off too frequently, causing wide temperature swings and inconsistent cooking.

Possible Causes
Temperature sensor too close to heating element, Loose thermostat sensing bulb, Poor contact between thermostat bulb and smoker wall, Control board hysteresis issue
How to Fix / Troubleshooting
Safety first: Unplug the smoker before adjusting any internal components.
Steps to stabilize temperature swings:
- 1. Check sensor or bulb placement: For digital models, ensure the temperature sensor probe is mounted in free air, not touching the element or metal surfaces. For mechanical thermostats, verify the sensing bulb is firmly clipped to the smoker wall in the correct location.
- 2. Secure loose components: Tighten any clips or brackets holding the sensor or bulb. A dangling sensor can read rapidly changing temperatures and cause short cycling.
- 3. Avoid blocking airflow: Do not place large pans or foil directly over the sensor area. Maintain clear space around the sensor for accurate readings.
- 4. Calibrate expectations: Some temperature swing is normal in electric smokers. Use an external thermometer to understand the average temperature over time rather than reacting to brief peaks.
- 5. Replace faulty sensor or thermostat: If the sensor or thermostat is physically damaged or gives obviously incorrect readings, replace it with an OEM Old Smokey part.
Note: Adding a thermal mass (such as a water pan) can help smooth temperature swings, but do not obstruct the heating element or sensor.
