Well yeah, but it might help to have something to compare it too. Unless you know what it should be? Hope if your going to chime in you might have a little more insight that what's obvious...

I missed your question earlier.
When I removed the blower, I tried to get everything as clean as possible and I did remove that plate and ran a vacuum cleaner hose in there. I checked it with a light shining from the blower housing end and a mirror to confirm it was clean all the way. There is some buildup on the inside of the pipe but not really bad. There is only 4' of exhaust pipe. When I checked both blowers with the manometer I had the exhaust disconnected. I checked the vacuum with the air adjustment open and closed.
I think both stoves are nearly identical. The vacuum on mine was about .25" with the old blower and less than half of that with the new blower. The paddle fan is not going to work as a replacement for the original squirrel cage.
I would assume it would be very close to .25, thats with his original assembly
Ok put the stove back to its original configuration. The engineers that designed it know more than you do.
I did replace it with the same part number. The replacement is a paddle fan and several members have verified that the replacement is working for them. It is possible there is another issue that I am missing.
Well, the replacement fan comes with a paddle, so I guess they were pretty smart huh? Also, mine, plus a few others have changed to a different brand paddle type fan, and have been fine. The original motor is rated at 85cfm, and the fan/motor assembly it was replaced with is also capable of 85cfm, so I'm not sure why you think it's the way it has to be. If it moves the same amount of air, the part moving that air doesn't mean squat. That's why he's trying to troubleshoot it as maybe another issue, because I have a feeling he could go spend $230 on the oem setup, and have the same issue. Although I'm sure your "insight" is appreciated, I'm sure there's a need for a troll elsewhere.
Not trying to be right, just trying to help a guy troubleshoot an issue, which so far all you have tried to do is make everyone else look stupid because obviously engineers have it all figured out, LMFAO. If they were that smart, they would of made a provision for easy cleaning on the original.
And that is exactly where this whole thing started. The need to remove the whole blower assy and clean the squirrel cage is a huge task, at least for me. It takes a few hours and then the blower is dirty again in less than two weeks.
Time to go look at that old tach and see if I can get it working.
I would bet that the original squirrel cage fan blade will fit that motor shaft. That would be another thing you could try. I don't think that's the issue, but just something to try if you really feel that's the cause. That motor is 3000rpm just like the original, so it will spin the same speed.
So far no luck in getting the set screw out. Heat, WD40 and still not budging. Broke off one hex bit in the set screw but got it out. Have you been able to remove it on your fan?
If you are still interested in selling your old fan let me know. I think that is my next step. I haven't been able to use this stove for nearly a month now.
I noticed there are two types of paddles for this fan. One has much deeper blades. The one I have has the shallower blades which is probably the reason it's not moving enough air.
This one has 9 blades

This one has 11 blades

Only thing is, more mass to rotate slows the motor down.

Yeah, just message me your email address, and I will invoice you, and ship it. Just figure $15 for shipping.
Also, sorry for the late reply. Not sure if someone got their feelings hurt or what, but I quit getting notifications for the thread. Guess I am just a big meanie!
Yes, mine came out easy, but wasn't that old. Maybe a Allen bit in an impact driver might help? Don't go crazy with the driver, but give it a couple hits on that, it may break it loose
I have not gotten any notifications either. Not sure why that would happen. I started a conversation so maybe you will get that.Also, sorry for the late reply. Not sure if someone got their feelings hurt or what, but I quit getting notifications for the thread. Guess I am just a big meanie!
I ordered the 9 blade and I will measure amperage before and after to see if there is a difference in load on the motor. The 11 blade appears to require a more substantial motor which they list as 1.75 amps.
What are the stats of your new motor? The 9 blade is identical to my quad fan. It should be fine with yours
Hope it works better. My stove, on heat setting 2 with the room blower on medium runs about 120 watts so right around an amp and that's with the 11 blade quadrafire style impeller. I did not check it with the original impeller I got with the motor, but the original motor and squirrel cage ran about the same wattage, and I would assume the universal impeller was about the same as it worked good as well, I just needed an impeller for my mom's stove, and wanted to try the quadrafire style one.
I think you'd be hard pressed to find a hp rating on most pellet stove fan motors, or at least the ones I've seen, but the amp rating on the motor is .95, 120v, 3000 rpm with the universal impeller, not sure what rpm it's spinning with the quadrafire 11 blade stye but it works really good.
