Hi all,
I have had an Avalon 900 ('93-'96) for ~9 years, have replaced most parts throughout the years, give the exhaust pipes and cleanouts a thorough cleaning every month or two, but am now running into a new issue I just can't figure out. Any insight you can provide in order to avoid running the electric baseboard heat is greatly appreciated!
Upon starting up the stove it may run just fine for anywhere from at least ~30 minutes, to a few hours, to even a couple of days before the auger motor will suddenly stop turning. Sometimes it's able to recover and resume turning before the flame goes out, and then keep going for a while before stopping again, sometimes not and the fire dies. Both the exhaust and blower fans run without issue.
I installed a brand new hi torque auger motor last week, but the issue persists. Also tried a brand new cycle timer yesterday, sprayed electrical contact cleaner into the burn rate dial, stripped and replaced the electrical connectors with new leads, yet same thing. I also have the negative pressure switch wires tethered together to rule out that factor.
Oddly, just now when it stopped turning (for ~30sec), I pulled the leads off the 220F snap disc, then reinstalled them and it cycled for an interval or two before stopping again. I then tested tethering the 220F snap disc wires together with a jumper to rule out a faulty disc, but the issue still persists; it'll go for a few cycles then pause for a while (~30-60sec before starting again, if at all).
There is no jam in the auger, I can turn it freely from the back without the motor on without much resistance (at most slightly gummy but nothing the auger shouuldnt be able to handle), and only have about 64oz of pellets in the hopper during these tests.
When the motor does stop turning, I do still hear the cycle timer "click" on at the intended interval, but don't hear any attempt in the motor to turn (not even an interrupted grunt, as if it were trying to force through a stuck bearing). It's as if its just not getting power for a few cycles despite the cycle timer still clicking at the proper rate. Sometimes the motor may give a faint half-second twirl instead of the normal 2.5 second rotation, and when it does somwtimes I hear a very faint squelch.
Again, it runs perfectly well, turning very strong upon startup, and with a vigorous flame for at least a full 30 minutes (sometimes more). Sometimes it may run for hours, overnight, or a couple of days before starting to intermittently stop.
Pulling my hair out. Naturally it died the night before each of our recent snowstorms.
Truly appreciate any insight you can provide.
