Control panel displays Er2 and grill shuts down or will not start; temperature reading is erratic or extremely high/low.

Safety first: Turn OFF and unplug the grill. Allow it to cool fully before touching internal components.

• Visually inspect the RTD cable: Look for melted insulation where the cable passes near the firepot, exhaust, or burner box. Any exposed conductor can cause a short.
• Check for pinched points: Open and close the lid while watching the RTD cable path. Ensure it is not being pinched by the lid hinge or side shelf brackets.
• Dry and clean connectors: If the grill was exposed to heavy rain or washing, disconnect the RTD plug at the control board and dry it thoroughly. Use compressed air and electrical contact cleaner if available.
• Measure resistance: With a multimeter, check the RTD resistance at room temperature. A reading near 0 ohms or wildly out of spec indicates a shorted or failed probe.
• Replace the RTD assembly: If damage or a short is confirmed, install a new Timberwolf RTD Temperature Probe Assembly, securing the cable with high-temp zip ties away from hot surfaces.
• Reset and test: Reconnect power, clear the error by cycling the main power switch, and run a low-temperature test cook to verify stable readings.
