I just got a JR love it the first bag I used was apple no issues what so ever. I now went to hickory and everytime I shut it down the pellets in the auger tube are burning. Is this a issue maybe with the hickory? Did it on high did it on med. I do clean my unit every 3 cooks vacum all the ashes etc so I keep it clean. It does seem that the hickory pellets are softer then the apple were. Thanks for any ideas to try.
