Clunk clunk

[Don glatts]

I have a 25th anniversary 2004 Harman pellet stove serial number 584 it started making a clunking noise every so often while the auger was grinding.
Now it's clunking once or twice a minute. Please let me know if this is something I can fix myself or suggest a good service guy in Southern California. Thanks Don

Take a look at the pellets you are "grinding" into the machine...overly long? Is the machine trying to cut them to size?

And as it's a 2004, there may be a modification or cleaning / lubrication that may need to be done. I'll try to do a search, but there are others on here much smarter than I that I hope will chime in.

Take a look at this thread:

Not that it might be the fix, but you never know.
