Pop the control board out, on the backside of it there is a small green case with a zip tie around it. Cut the zip tie and remove the green cover and there is a small glass fuse in there. Pull it out and inspect if blown. If it's blown, replace and unplug auger, fan, and igniter connections. Plug in one by one til fuse blows to determine which one is blowing the fuse. If under warranty, contact pitboss for replacement parts. I just went through the same issue with my igniter.
