Draft inducer obsolete: alternative repair strategy

slateroof · January 10

Recently posted about my Buderus power vent replacement. (Jakel-Ametek 117438-03, blower assembly 7121-8998). I have contacted Buderus, SupplyHouse, the Warehouse, Electric motor Warehouse, and Ametek. All were helpful but have no replacement units, nor motors. Looking online, there must be a hundred different draft inducer units from many manufacturers. Surely there must be some replacement motor for this unit.

About twenty years ago, I had a far easier time finding circulator motor parts for a much older hot-water boiler. Must be the zero-inventory approach to business these days!

You could take that to a motor shop and get it rebuilt.

The heating industry is doing itself no favors with this low inventory and proprietary parts nonsense.

that will be real expensive!

What is his alternative?

pecmsg · January 11

not many.

Only other thing is to keep looking on ebay for parts.. Facebook marketplace for an old unit or craigslist.

Is it possible an old supplyhouse out there has old stock?

How would you get access to that information?

Have you called Buderus?? Its probably a longshot though.

I am sure another vendor made those for Buderus. Chances are they used the same thing on other MFG boilers. Maybe European boilers

You did not post a picture of the information on the motor (so big guess below on my part). You posted "blower assembly 7121-8998".

I found this "type U21B".

Maybe you can do a motor transplant.

There may be better choices, like on eBay, search for "U21b motor" many there. See if there is anything you like there.

Thanks for all the comments!

That FASCO motor on Amazon is beyond pricey!!! But the alternative is to scrap the Buderus altogether… which may be realistic because these older units have no parts support since Bosch acquired Buderus. (Have already struck out on the manifold B-kit)

pecmsg · January 11

they have no parts because they’re old and obsolete!

if they’re only going to sell a handful of parts, of course it’s going to be expensive

i think @109A_S found what you need. now the question is weather its worth investing that money into it. don't procrastinate too long. if your having a hard time finding it now what are you going to do when it craps out 100%.
