I purchased a Big E about a year ago. This is its second season of use. My problem is that the stove will not turn on at all. If I unplug it, then plug it back in, the circulating fan will kick on for about a sec, then shut right off. I have bypassed all the snap switches to see if one of them was the problem. When I jumped the wires connected to the snap switch on the combustion blower, the stove will come on and burn for about 15 min. Then the auger will stop feeding pellets and both fans continue running. Can anyone lend me a hand?
