My father in law purchased this Traditions by The Earth Stoves a few months ago. The combustion blower is gone, the previous owner said it would cost about $250 for a new one. I looked into a couple of different companies and they want $550-600+ for this 90 cfm draft fan. The part # 38122. These stoves were built from 1998-2000. The stove is in really good shapefrom the outside. It is black enamel and has beautifully clean glass. the burn pot is absolutely huge and looks like 1/2 inch steel. He took the rear panels off and we unveiled the access panel for the exhaust passage that comes after the blower motor. The thing was caked up with ash! I think as much as half way full if not more, no wonder the thing failed. The motor was still spinning very smoothly so we both agreed the best thing to do would be to take it all apart clean it all (it was all extremely dusty), take the motor off and try to clean it as much as possible then give it a test run. He will bring the motor to his buddy to have it tested before buying anything. My question is, could this motor be that much of a rarity that it's worth over $600 to some people? It just seems like there should be an aftermarket part of some sort that could fit this thing. All I could find were Lennox original motors to match that part.
 
If the motor spins easily by hand it's not the motor, it's power/lack of going to motor
most pellet stove motors are the same 3000 rpm, usually a Fasco motor, just the mounting is different, which can be removed and modified
 
Chris,

Post all of the numbers on the motor plate, likely there are tons of motors out there that match it and the impeller should be able to be moved to a new motor (the impeller is the part that primarily determines air flow). You just have to make certain that what you get doesn't exceed the controllers capability to power.
 
Current Lennox Part # H7310 (combustion blower for Montage) should be a direct replacement and shouldn't be anywheres near $500
 
If you cant find a replacement for it, A motor repair shop should be able to rebuild yours for a lot less than $500, more like $100.
 
I'm noty sure that other motor would fit in the space where the motor goes in that TP300. It is a tight squeeze and the EBM motor is very low profile. Of course before he spends an extraordinary amount of money on the original part all otherr options will be explored including getting measurements for those other possible motors and seeing if they might fit. He is just now thinking about getting it going for perhaps next winter. He has two wood stoves that are heating the house just fine, one of them will be replaced by the Traditions TP300, the other will remain in use and is on the main floor of his raised ranch.

We both agreed that the first step would be cleaning it up and trying to get it going. He has not even plugged it in yet. But when the stove was bought the previous owner said the motor was gone. The next step would be testing the motor if it won't work and there is power going to it. Someone else told me that if the motor was replaced with something different the capacitor would have to be transplanted to it from the old motor.

I'm still curious as to the cost of the original motor, seems very unusual but at least one of the sources was a known company I've heard of before. They wanted about 570 for it and that was the lower of the two prices I was able to get.

I'll get the numbers from him tomorrow. I had a piece of paper with some info on it but can't seem to find it anywhere.
 
This motor is pretty cool in a lot of ways. First, it is symmetrically balanced, requires a capacitor to start and has an optional hall sensor mounted inside, whereby it can measure the RPM. Hall sensors are pricey. If the motor won't start on it's own, give it a little spin at start up. If it will continue spinning on it's own after a little help, then you only need to replace the capacitor. Those are cheap. If the control board isn't reading that the motor is spinning, the hall sensor may have gone south...but that is not usually the case. Ebm motors are serviceable if you know what to look for and where to look.

Check out the spec. motor is on p. 10 of the PDF

Any Austroflamme Intergra motor should work too, for about $299.00
 
Thank you Scott for the great information. He agreed that the first thing would be trying to get it to work, he has not even plugged it in yet. It is no wonder it was not working, upon opening the access to the exhaust passages in the back of the stove, which is a nice feature I might add, it was more than half way filled with ash! After he vac's it all off and tries to get it going he will have the motor tested. I'll make sure to keep posting back here with updates. His motor is more like the one on P. 13 of that link you sent me. It is a .3 amp motor from what I remember with similar rpm's in the 2000's. He still has not gotten back to me with all the specs on his motor, but I remember those numbers vaguely. Again, thanks for the info!

We drive through your neck of the woods several times a year on the way down to Westport and Horseneck Beach. We love it there!

Take care,

Chris
