Possible Causes

RTD sensor partially open, Poor sensor connection at control board, Sensor not fully inserted into cook chamber, Control board calibration fault

How to Fix / Troubleshooting

Safety first: Unplug the smoker before accessing internal wiring.

Steps:

  • Check sensor placement: Verify that the RTD probe is fully inserted into the cook chamber and not pulled back into the insulation or cabinet wall.
  • Inspect and reseat connector: Remove the rear panel and locate the RTD connector on the main control board. Unplug and replug it to ensure a solid connection.
  • Test sensor resistance: With the sensor disconnected, measure its resistance at room temperature and compare to specifications. A significantly higher than normal resistance can cause low readings.

Repair: Replace the RTD temperature sensor probe if resistance is out of spec or intermittent. If a new sensor does not resolve L1/LO, the main control board may require replacement.
