Traeger hopper sensor

Traeger pellet sensor alerts

A pellet-level message is only useful when it belongs to a grill that actually has a pellet sensor. Start with the exact display and controller family before treating it as a fuel-feed failure.

Confirm the sensor and family first

D2 WiFIRE

Traeger documents a separate calibration path for D2 WiFIRE grills. A low reading with a full hopper can call for calibration, but only where that menu and sensor are documented.

Touchscreen Timberline and Ironwood

These newer models use a different sensor system. Traeger says the D2 calibration routine does not apply; follow the touchscreen notification rather than searching for a hidden calibration control.

Woodridge models

Woodridge Pro and Elite may show their own pellet-sensor displays, including ER28 for a disconnected sensor. Keep the exact model and wording with the official support path.

Name the message before taking action

01

Low pellet level

A low-level notice can simply mean the hopper needs pellets. It does not automatically mean the auger is jammed. If the hopper is full but the number remains implausible, use only the documented sensor check for the controller family.

02

Calibration error or inaccurate level

For the D2 path, Traeger first limits the check to an unplugged, cool grill and a clean sensor lens before calibration. Do not transfer that routine to touchscreen or Woodridge models.

03

Disconnected sensor display

An error such as ER28 is not a universal Traeger code. Record it exactly, confirm the model, and use the matching official article. This page does not establish a wire, connector, or replacement sensor.

What the official material supports

Traeger’s documents establish different sensor messages and scopes for D2 WiFIRE, touchscreen Timberline and Ironwood, and Woodridge models. They do not make every Traeger pellet-sensor compatible, turn a low alert into a diagnosis of the auger, or authorize a generic replacement procedure.
