Hi, I've had a Harman XXV for about 6 weeks now. I'm not new to pellet stoves, had 2 before at previous houses. But, this is my first problem like this. Two days ago, the auger started making a horrid high-pitched screeching sound each time it turns. I've thoroughly cleaned the stove, and I see no sign of the auger scraping the sides of the tube, at least in front (not 100% sure about in back). The noise is loudest out the back of the stove, and it goes away while I am pressing my hand against the back of the auger motor, only to start immediately again once I release my hand. It is quite unbearable, makes my ears hurt within a few minutes. The local pellet stove store is booked up for appointments, and this was intended to be my primary source of heat. Its not some novelty item that I can merrily wait around for over a week for someone to show up. I've been trying to fix the noise, and also have been making several trips to/from the pellet stove shop to discuss this with them. I'm thinking that either the auger isn't aligned properly in the tube, or there's a pellet wedged against the back end of the auger that is scraping. (Although if that's the case, wouldn't friction wear out the wedged pellet and sound go away? It is getting louder.) I opened up the panel that lets me clean out the fines that collect back there, and vacuumed them out. From what I can see, it looks fine in there but my visibility is terrible so I can't be sure. So, I've been trying to remove the motor and then the auger. I have a corner installation. I haven't been able to get a tool properly onto the set screw for the auger motor well enough that I can apply sufficient force to budge it. There's hardly any room at all the work back there. I've tried socket extensions, including a flexible one. I've tried the auger in different positions to move the set screw to different places to try to reach from other directions. I'm stumped! I have no idea how to get this thing off. What do people do? Assuming I can get that off, then how would I reach the two bolts that hold on the flange? I can see them, barely, but that's about it. They look even more inaccessible than the set screw. What would people recommend?
