Have you gotten a low pellet level notification, only to open the hopper and see that it's still practically full but has just created a funnel shape in the middle? Or have you run out of pellets in the middle of a cook? Let's review what to do when you run out of pellets, and let's introduce you to a term called, "tunneling."
Tunneling is a term we use when the pellets in the hopper create a funnel-shaped void while feeding pellets into the grill. The grill basically feeds all the pellets in the middle of the hopper but leaves a large collection of pellets on the sides of the hopper.
While newer grills have improved design to reduce this from happening, it still occurs occasionally, particularly in small cavity grills like the Junior, Tailgater and Bronson models. If you find that your pellets are tunneling, try the following:
While tunneling is a false alarm of sorts, it's still possible that you will actually run out of pellets during a cook. If you do run out of pellets in the middle of a cook, don't worry: getting back grilling is easy.
