Display shows “Er1” and grill will not start heating.

Safety first: Unplug the grill and let it cool completely before working inside the hopper or control area.

• 1. Check RTD connection:
  • Locate the RTD probe wire entering the hopper and connecting to the controller.
  • Ensure the plug is fully seated and not partially pulled out.
  • Disconnect and reconnect the plug several times to clean contacts.
• 2. Inspect RTD cable:
  • Follow the RTD cable along the cook chamber wall.
  • Look for cuts, crushed spots, or melted insulation from contact with hot surfaces.
• 3. Test RTD with multimeter:
  • With the RTD unplugged, measure resistance across its two leads.
  • An open circuit (OL or infinite resistance) confirms a failed RTD.
• 4. Replace RTD probe:
  • Remove the mounting screw or nut holding the RTD to the cook chamber.
  • Pull the old probe and wire out carefully.
  • Install the new Traeger RTD temperature probe, routing the wire away from direct flame and sharp edges.
  • Reconnect to the controller and test.
