Display shows ErF and grill will not heat or shows wildly inaccurate temperatures.

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

• Step 1 – Inspect probe in cook chamber: Locate the ASMOKE temperature probe on the side wall. Clean off heavy grease buildup with a damp cloth once the grill is cool. Do not use abrasive tools that can damage the probe.
• Step 2 – Check wiring: Follow the probe wire into the body of the grill. Look for cuts, melted spots, or areas where the wire is pinched by sheet metal. Repair or replace as needed.
• Step 3 – Verify connector at controller: Remove the controller and ensure the RTD sensor plug is firmly seated. Reseat the connector several times to wipe oxidation from the contacts.
• Step 4 – Test resistance (advanced): With the grill unplugged, disconnect the RTD from the controller and measure resistance with a multimeter. At room temperature, most ASMOKE RTD sensors will read in the hundreds of ohms (consult your model’s spec). A reading of 0 Ω (short) or infinite (open) indicates a bad probe.
• Step 5 – Replace probe: If the probe is physically damaged or tests bad, install a new ASMOKE temperature probe / RTD sensor compatible with your model.
