Possible Causes

Disconnected RTD temperature probe, Broken RTD probe wiring, Failed RTD sensor, Corroded connector at control board

How to Fix / Troubleshooting

Safety first: Unplug the grill before handling wiring or the controller.

  • Step 1 – Locate RTD probe: Inside the cook chamber, find the metal temperature probe mounted to the side wall. Follow its cable back through the body to the controller.
  • Step 2 – Check connections: Remove the controller from the hopper housing. Locate the RTD connector on the control board and ensure it is fully seated. Disconnect and reconnect to clean the contacts.
  • Step 3 – Inspect cable: Examine the RTD cable along its entire length for cuts, melted insulation, or pinch points where the cable passes through metal. If damaged, replace the RTD probe assembly.
  • Step 4 – Test with multimeter (optional): With the RTD disconnected and grill unplugged, measure resistance across the RTD leads. A typical RTD will show a finite resistance (often 100–2000 ohms depending on type). An open circuit (infinite resistance) indicates a failed probe.
  • Step 5 – Replace RTD probe: If the probe or wiring is damaged or tests open, install a new Louisiana Grills-compatible RTD temperature probe and reconnect to the control board. Clear the ErF code by cycling power.
