It has been reported to me that some of these Breckwell stoves have an orange wire that goes to the auger that is routed under the combustion air intake pipe and the wire gets pinched after years of use. If your stove continuously feed pellets (after warm) I would check that wire. Freestanding units mainly. It has been reported that if the manual auger switch is pressed while wire is shorted the fuse may blow or a spark is seen in the rear of the stove.
