Pellet Level Low
If you get a 'Pellet Level Low' notification on your Traeger App or controller saying your pellet level is low, but your hopper is full, calibrate your pellet sensor.
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.
- Turn off and unplug the grill.
- 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.
- Turn on the grill and attempt calibrating the pellet sensor again.
- If the grill continues to throw the Calibration Error, check the pellet sensor wiring connections.
- 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.
- Locate the black pellet sensor connection on the back of the controller and make sure it's fully connected.
- Follow the black wire to find the white molex connection and make sure the connection is secure.
- Plug in and power on the grill. Attempt to calibrate again.
- If the Calibration Error continues, replace the pellet sensor or contact Customer Support to troubleshoot further.
Does Calibration Error Affect the Grill's Functionality?
This error won't prevent you from using your grill.
