When Should I Calibrate My Pellet Sensor?

Most users only need to calibrate their pellet sensor before first use and after installing a new sensor. 

You may also want to calibrate your pellet sensor if it's not reading correctly.

How to Calibrate a Pellet Sensor

**The calibration feature is available on D2 grills only. New touchscreen Timberlines and Ironwoods have newer technology that does not require calibration.**

Once you install your pellet sensor, you'll need to calibrate it to get the most accurate results. Follow the steps below or watch this video:

  1. Empty your hopper and clean the pellet sensor, making sure there is no dust on the lens.
  2. Power on the grill. 
  3. On the controller, navigate to Menu > Pellet Sensor. You will see a message saying, Calibrate your pellet sensor for accurate results.  
  4. Select Calibrate Now by pressing the controller knob.
  5. If you haven't already, empty your hopper and clean off the pellet sensor lens. Select OK by pressing the controller knob. 
  6. Select OK to calibrate the empty hopper. 
  7. The controller will display, "Empty hopper calibrated. Press OK to continue." Press the controller knob to select OK
  8. Place your hand under the Pellet sensor to block the pellet sensor light, indicating to the sensor that the hopper is full. Select OK while your hand is under the sensor. 
  9. Your pellet sensor is now calibrated. 
  10. Refill your hopper with fresh pellets and Traeger on.

Calibration Error

In rare cases, you may get an error when calibrating your pellet sensor that says:

Pellet Sensor
Calibration Error 
Press OK to start over

This calibration error only appears on the grill's controller; it doesn't get pushed to the Traeger app.

  1. Turn off and unplug the grill.
  2. Clean the pellet sensor lens using a clean cloth. Pellet sawdust can build up on the sensor's lens, but not to the extent that you need to take it apart.
  3. Turn on the grill and attempt calibrating the pellet sensor again.
  4. If the grill continues to throw the Calibration Error, check the pellet sensor wiring connections. 
    1. Turn off the grill and remove the controller by unscrewing the 4 screws securing it to the hopper. The grill must be off when unplugging the sensor and plugging it back in. If the pellet sensor is connected while the grill is on, it will not work until rebooted. 
    2. Locate the black pellet sensor connection on the back of the controller and make sure it's fully connected.
    3. Follow the black wire to find the white molex connection and make sure the connection is secure.
  5. Plug in and power on the grill. Attempt to calibrate again. 
  6. If the Calibration Error continues, replace the pellet sensor or contact Customer Support to troubleshoot further. 

Can I Still Use My Grill if I Have a Calibration Error?

This error won't prevent you from using your grill.
