Err, Er1, Er2, & Er4 Error Codes

What's in This Article?

This article reviews why your Traeger pellet grill got an Err, Er1, Er2, or Er4 error and what you should do to resolve them.

Note: These errors will appear only on Traeger pellet grills without WiFi connectivity.

 

Err & Er1

Causes

There is a bad connection or a complete disconnect between the RTD probe and the control panel.

What to Do

Ensure that the connections look good. Check the RTD connection by following these steps:

  1. Turn off and unplug your grill.
  2. Remove the two Phillips-head screws holding the controller in place.
  3. On the back of the controller, loosen the flathead brackets on the green box that hold the RTD wires in place.

  4. Completely disconnect the RTD wires from the green housing box. You do not need to unscrew the screws completely.

  6. Place the controller back in place and screw in the two Phillips head screws you removed earlier.
  7. Plug in the grill and turn it on. The error should no longer appear.
  8. If the Err or Er1 codes still appear on the controller, please call Customer Service.

Er2

Cause

An ER2 error message indicates that the RTD probe (i.e., temperature sensor) has failed.

What to Do

Replace the RTD. Contact Customer Support to verify and order.

Er4

Cause

An Er4 error message means that the induction fan has been disconnected. 

What to Do

  1. Check the fan connection.
    1. Turn off and unplug your grill.
    2. If your hopper has a bottom service panel, remove it by unscrewing the screws securing it in place.
    3. Locate your draft induction fan. If having difficulty, find the orange wires and follow them to the fan.
  2. If the fan is connected but Er4 still appears, contact Customer Support.
