So I have a new Englander and after an hour of it running nice it decides to act up. It stops feeding pellets into bottom auger which causes me to open hopper,shuffle pellets around basically do anything to keep chamber box hot. The auger will go again but eventually act up. I know it's intermittent but just not feeding properly. I'm off to by New motor. Could motor be getting tired? It's weird to buy one when stove runs good for hour or so
