Possible Causes

RTD probe shielded from heat by foil or pan, RTD coated in thick grease, RTD located in a cool corner due to modification, Control board misreading sensor

How to Fix / Troubleshooting

Safety first: Use caution when opening a potentially overheated grill; stand back from escaping heat.

  • Step 1 – Remove obstructions: Ensure no foil, pans, or accessories are blocking airflow around the RTD probe.
  • Step 2 – Clean RTD: Remove heavy grease and soot from the probe.
  • Step 3 – Verify with external thermometer: Place an oven thermometer at grate level and compare readings.
  • Step 4 – Reposition accessories: Avoid placing large pans or deflectors directly in front of the RTD.
  • Step 5 – Replace RTD or controller: If the display remains significantly lower than actual temperature, replace the RTD, then the control board if needed.
