I've had an older Austroflamm Integra pellet stove for a few years now, and had to put it aside for a few years as it developed some problems that at the time I couldn't diagnose, and couldn't afford to fix them if I had.
Luckily I had a backup pellet stove an old Avalon that works well enough, but isn't anywhere near as good as the Austroflamm.
I recently figured out that the auger was at least a major problem in the way it had been acting. The shaft inside the large gear was spinning in the center of the gear, but would catch enough to spit out pellets erradically.
Here is the current problem I am having. I have replaced the Air Sensor and the combustion motor speeds up and slows down, except it seems if you open the door it will not return to the slower speed afterwards.
I did the diagnostic bypassing the LT switch and the voltages I have found are a little high from what the downloaded manual states they should be. I turned the potentiometer down as far as it can go, and here are the voltages.
At low setting the voltage is 48.4 to 48.5 volts. At max setting it goes to 65 to 77 volts, and with the door open it goes to 123 volts.
Is this a problem with the Main Board?
I have completely cleaned the stove including all the hidden little spots.
Sorry for the long post.
