Pellet stove is in my sign, got it new from home depot. I vacuumed it every day, what happens is the stove just goes out. Even on settings 9 and 9 just will work then go out. I'm guessing on the biggest setting it shouldn't be doing this unless the temp us high enough to shut down. My house was 60 degrees and the auger quit feeding fuel apparently! First found iyt last night, had the hopper full, heat at 3 fan at 5 went to bed. Woke up to a 55 degree home and pellet stove that shut down with a semi full hopper. Ugggh, is it a setting somewhere on the last 3 factory buttons? This is too sooner for a pellet stove to act up. I will try cleaning ignited when the stove decides to shut down again. Please help
