What I do is I suck out the venting outside with a leaf blower 2 times a year and I cut a length of garden hose that fits into the reducer adapter on my shop vac and I use the hose to get back of the exhaust fan plenum.
I found my issue was between exhaust fan and the unit, not going to the chimney , Its a hard spot to get to. Let us know how it goes and get the draft set right.
I can't believe I missed knowing about them, or that the stove ran so well for so long! We burn 3-4 tons per year and are on our 7th year! We ran it for our entire small ranch on level one or two most days/nights, but with the traps blocked we had to run it on 2-3 more often this year - seems to be running much hotter now. I hear a lot of bad reviews for this model but overall for us it's been a great stove and I wouldn't hesitate to buy another. The exhaust motor has been acting up a bit the last couple years. I ordered a replacement from pellethead.com but it doesn't spin as fast and gives a E2 error code. I think it may be because the original is 1.35 Amps and the replacement was 0.85 amps. The original was tuning hard with a lot of resistance, so I took it apart and cleaned the part that spins inside the magnetic block, with brake fluid! Dried it well, now it spins perfectly again. We'll see if it holds up. I feel like I'm working on an old car again - lol.Good you got it solved. Those are the side ash traps I mentioned. Not cleaned in 1000 bags wow. I clean mine about every 50 bags or so. About every other time I clean the firebox.
Can you explain this in more detail or show an image of where that would be? "You need to pull the outer bearing retainer from the field laminations "You need to pull the exhaust blower (combustion fan) and oil the bearings. Brake cleaner is no good for any motor. it' sucks the oil right out of the bearings. I did a thing post a while back on just that. You need to pull the outer bearing retainer from the field laminations and oil the bearing with light machine oil and it it's a shielded bearing (dust shield, pop the shield off with a small pointed tool, oil the races and replace the shield and reinstall the retainer. You won't be able to pull the shield on the inner bearing but a good soaking with light machine oil will seep into the bearing and lube it. I oil all my bearings on every motor, convection fan, combustion fan and auger drives, every spring when I give the unit it's spring shutdown cleaning. Never use brake cleaner or any dry solvent on a motor. Big no no.
OK thanks, I'll give it a shot. Is this on the outside of the motor where the small black flywheel is located?I'm not photogenic. Just look at the end of the fan/drive motor. There is a bearing retainer there held on with 2 screws (usually T20 Torx), remove them and remove the retainer and oil the captured bearing.
