The other day the stove was running fine, it has been for years. I came back in the house and it was humming. Shut it down pulled it out and cleared the auger as I assumed it was jammed. Put it all back in turned it on and it ran fine for about 5 mins then blew the fuse. Unplugged all four items and plugged them back in one at a time. The fuse didn’t blow until I plugged in the green ground to the distribution motor. Replaced the fuse turned it back on and the fuse pops instantly. Anything on this?
