Hi All,
I have a Lopi AGP (installed 2015) that's acting up. After failing to light once, I tried again last night with no success. The lower/horizontal auger was rotating, but there were no pellets getting pushed forward. Also heard a slight *click-click-click* noise that sounded a little like a gear skipping against another tooth. Figuring that it was a dreaded pellet jam, I cleaned out the pellets and opened the access plate to look to clear the jam.
That's where things got weird. There wasn't a visible pellet jam. Nor was the HRD even close to being jammed (See attached pic). HOWEVER, the HRD was no rotating. I could see it straining to rotate only to give a slight shutter with ever click.
So, a few questions:
1) Is it possible for an HRD to jam from the bottom where it drops into the auger track?
2) If so, can I just undo that visible bolt and lift the HRD up and clean below? Or do i need to pull the unit out from the fireplace and get at it from behind?
3) The Lopi trouble shooting guide says (in big red letters) not to just put a wrench on that bolt and force it. Any guesses as to why?
4) I get the sense that the HRD motors give out over time, does this just need to be replaced or does this seem repairable?
Any thoughts would be greatly appreciated,
Andrew
