how to clean aire-flo blower?


I have an aire-flo upflow furnance that I want to get cleaned out, I already cleaned all the other parts (didn't touch the gas nozels though) but the blower I can't seem to figure out how to get out to clean... you can take the face plate off get to where the blower is but there are no rails to slide it or or anything... anyone know the procedure to clean the blower on this brand furnace?

how to clean aire-flo blower?


Post a pic of it with the doors off. Have to dismantle 1/2 the furnace to get the blower out. Have to remove the electrical compartment and wiring etc. Huge pain in the arze.

Take the bottom panel off the blower section and you will see the blower.

Look around inside and you will see how it mounts...it will either slide out on rails or there will be hex head bolts or sheet metal screws holding it in place.
The blower assembly will drop down from a rear flange.

These two methods of rail or flange mount might seem difficult at first. But don't be afraid to take any bolts or screws loose till you find the right one.

Once you get the assembly out you will see a set screw holding the wheel to the shaft.

Loosen that and remove motor mount screws or bolts and pull the motor from the shaft.

You will then have access to clean both side of the blower wheel.

awesome thanks, what do you recommend for cleaning the blower wheel? I've seen some day spray it with a hose others say vacume it...

how to clean aire-flo blower?


A good stiff bristle brush like a tooth brush. I don't recommend wire bristle because it will scratch the rust resistant finish. No need for fancy cleaners unless there are smokers residing in the home or cooking oils have made it sticky.
Then a good degreaser would be in order. Fantastic or 409 spray is good but you may have to use a bit more elbow grease.

i use a method i will share with you but it's only to be used as a lost resort cause if applied improperly you ruin the blower wheel.

Liquid dish soap like Dawn is a helluva grease cutter. Mix a 50-50 solution and apply liberally to the concave (groove shaped) blower vane with the brush .
Allow a moment to work and then clean out dirt build up with the brush and a clean rag. Dry thoroughly or the vane will rust.

This is time consuming and tedious so be prepared.

Another method that works but i don't use is taking the blower assembly to a quarter car wash. Same precautions as the Dawn dish soap cleaning apply.
But in this case not only do you have to Dry thoroughly. you also must make sure the pressure doe not run the rust resistant finish of the blower wheel.

Good luck

And don't use a hammer to force the wheel off the motor shaft.
