I have a England stove works pellet stove, I bought it used last year it ran great and I was running great this year until tonight! When the stove is in SU mode everything works great,But soon as it comes out of start up mode the auger feeds pellets maybe for another minute and then it just stops feeding pellets and the fire dies! It doesn’t make any sense on why it would work and start up mode but once it gets out a start up mode it shuts down! Please help!
