Hi, new here, and hoping I can find some advice. We have a vistaflame fireplace insert. At the end of last season, the blower stopped kicking on literally at the last bag of the season. It fires up, the auger drops pellets, and the flame gets going with the small fan at the start. But when the big blower should kick on, to disperse the heat throughout the house, it does not any more. It doesn't come on and the fire of course burns itself out cause the stove shuts itself down. Any suggestions? We love our stove but are in KY and there is literally noone I have found who knows a darn thing about these stoves..... GRRR! So I suppose I'm gonna have to try to fix this one myself. We haven't been all that diligent about major cleaning short of vaccuming obvious ash (I know, I know). Could build up be a culprit here? Thanks for the help in advance!
