Possible Causes

Lid thermometer out of calibration, RTD probe location different from lid gauge, Heat stratification inside cook chamber, Faulty lid thermometer

How to Fix / Troubleshooting

Safety first: Use caution when touching thermometers; they can be hot.

  • Understand that the lid thermometer measures air near the lid, while the RTD probe measures at its own location; some difference is normal.
  • Test the lid thermometer in boiling water to check calibration; replace if significantly inaccurate.
  • Rely primarily on the digital controller and meat probes for precise cooking temperatures.

Warning: Do not attempt to bend or force the lid thermometer; replace if damaged.
