Display shows L1 and temperature reading is extremely low or stuck at minimum despite heat

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

• Step 1 – Check RTD connection: Remove the controller and locate the RTD connector. Ensure it is fully seated. Disconnect and reconnect to ensure good contact.
• Step 2 – Inspect cable and probe: Look for any cuts, burn marks, or pinch points along the RTD cable. Inspect the probe inside the cook chamber for physical damage.
• Step 3 – Resistance test (optional): With the RTD unplugged and grill off, measure resistance across the RTD leads. An infinite reading indicates an open circuit and a failed probe.
• Step 4 – Replace RTD: If the probe is open or visibly damaged, install a new Louisiana Grills-compatible RTD probe and route the cable away from hot surfaces.
• Step 5 – Evaluate controller: If a new RTD does not clear L1, the control board may have a failed sensor input and should be replaced.
