Hi im new to pellet stoves and i bought a used breckwell p24fs. Its older it has the manual control board, the only date i can find on it is 1995. it worked fine for a while then the convection fan went (it was making noise when i bought it so i knew it was a matter of time) so i replaced the fan with a direct replacement and it ran flawlessly up until a few days ago it started shutting down intermittently. It will shut down faster if i turn the feed rate up, but whenever it shuts down it kicks back on in a matter of minutes if not seconds but the auger doesnt reset so the fire dies. Would this be a hi/lo limit switch issue? Or maybe a vacuum issue? Im no professional so anything helps. Thanks in advance
