Display shows “Er2” and grill shuts down or will not start.

Safety first: Disconnect power before handling wiring or the controller.

• 1. Inspect RTD wiring:
  • Trace the RTD cable from the probe to the controller.
  • Look for spots where the insulation is rubbed through or melted, especially where it passes through metal.
• 2. Check connector:
  • Unplug the RTD from the controller.
  • Inspect the connector for bent pins or debris causing a short.
  • Straighten pins gently if needed.
• 3. Test RTD resistance:
  • Measure resistance across the RTD leads at room temperature.
  • A reading near 0 ohms indicates a shorted probe; replace it.
• 4. Dry out moisture (temporary measure):
  • If the grill was stored in heavy rain and the RTD looks wet, allow it to dry for 24 hours in a warm, dry area.
  • If Er2 persists, replace the RTD.
• 5. Replace RTD:
  • Install a new OEM RTD probe and route the cable to avoid pinch points and hot surfaces.
