Display shows “Er3” and grill will not operate.

Safety first: Unplug the grill and ensure the firepot is cool before working near the hot rod.

• 1. Check hot rod connector:
  • Access the underside of the firepot or inside the hopper where the hot rod plugs into the harness.
  • Ensure the hot rod plug is fully seated and not burned or melted.
• 2. Test hot rod resistance:
  • Disconnect the hot rod from the harness.
  • Use a multimeter to measure resistance across the two hot rod leads.
  • Typical Traeger hot rods read around 40–60 ohms. An open circuit (OL) means the hot rod is bad.
• 3. Inspect wiring:
  • Check the hot rod wires for burns or cuts where they pass near the firepot.
  • Repair or replace damaged wiring as needed.
• 4. Replace hot rod if failed:
  • Remove the grates, drip tray, and heat baffle to access the firepot.
  • Remove the screws securing the firepot and gently lift it to expose the hot rod.
  • Slide the old hot rod out and install a new Traeger hot rod igniter, routing wires away from direct flame.
• 5. If Er3 persists with a good hot rod:
  • The controller’s ignition circuit may be damaged; replace the main control board.
