Controller display shows ER-1 and grill will not start or shuts down shortly after startup.

Safety first: Unplug the Recteq grill from power and allow it to cool completely before working near the firepot or wiring.

Steps to troubleshoot ER-1:

• Inspect the RTD probe: Locate the RTD (temperature sensor) inside the cook chamber, usually on the left side wall. Check for obvious damage, kinks, or cuts in the stainless probe or its wire.
• Check RTD wiring and connector: Follow the RTD wire through the rear of the cook chamber into the controller area. Ensure the plug is fully seated on the controller board and that no pins are bent or corroded.
• Test continuity (if you have a meter): With the grill unplugged, disconnect the RTD from the controller and measure resistance across the two RTD leads. A typical RTD for Recteq will show a finite resistance (often in the hundreds of ohms). An open (OL or infinite) reading indicates a failed probe.
• Reseat or replace: If the connector was loose, reseat it firmly and try powering the grill back on. If the probe is physically damaged or tests open, replace the RTD temperature probe with a compatible Recteq RTD assembly.
• Re-test: After replacement, power the grill, clear the error by cycling power, and verify that the display shows ambient temperature instead of ER-1.

When to stop: If a new RTD does not clear ER-1, the controller input circuit may be damaged. Do not bypass safety sensors; contact Recteq support or a qualified technician.
