Inducer installation / modification ...
 
1 Attachment(s)
I received my Fasco A142 inducer and the first thing I did was remove the old inducer and installed this new one to make sure it worked...and it did! A special thanks to #Carrierman for his assistance in making sure I had the correct inducer...Thank you.

The inducer installation setup on my furnace is such that the inducer blows upward and thus the factory installed drain (sealed unless punctured by installer) is in the wrong position...it is not at the lowest point. A notice related to the inducer is that the installer will have to drill a new drain hole if mounted in a different position. The inducer does have drain locations indicated on the housing if this is the case.

The positioning of the drain nipple protruding horizontally out from the inducer housing makes it difficult to install the nipple I have due to the precise placement of the drill hole to insure the drain is positioned to properly drain the condensation along with the fact that the thickness of the housing is thin.

I an considering reinforcing the bottom of the housing with a 3/16 thick piece of ABS drain pipe that I had cut and heated to conform with the radius of the housing...as is seen in the photo. This piece would be adhered to the housing with ABS cement. I would then mount the drain nipple vertically into the bottom of the inducer housing. I would then have enough thickness to support the nipple attachment and would be able to trim any portion of the nipple the protrudes into the interior of the housing to ensure that the condensation drains out the bottom.

Then I can attach the tubing that had attached to the old inducer for piping away the condesation.

Any thoughts or suggestions before I continue...???

Thanks, Casey

Here is another picture further illustrating what I am doing...

Its the WRONG inducer, if you modify it in any way shape or form you do two things, accept all liabilary and void any warrentys.

What is on the furnace is a Fasco 7162-3136...what do you suggest is the correct inducer? We have a horizontal gas furnace, Carrier 349MAV036075.

You got a camara.....post a picture of the old motor and the furnace it goes on.

Here are two photos...it is difficult to include the whole furnace because it is under the house (5 foot tall crawl space) and the air ducts prevents being able to see the furnace.

Yep.........you need to take that motor back and get one with the drain plug in the correct postion.

Could you help me in identifying the Fasco model number of the inducer with the drain in the correct position? ...'preciate your time and expertise in the solution of this issue.

You have to go to a carrier dealer with your model and serial number and they can order the correct one........I have to admit that in 22 years i have never seen a "Carrier" inducer that looks like that. It looks more like a junk rheem or ruud.

acefurnacefixer....

Therein is the problem. I have contacted numerous Carrier/Bryant dealers and each one said that there is no oem inducer for our furnace model. ( The furnace is now 14 years old.) One dealer called me back saying he spoke with a distributer on the East Coast saying that there is no oem inducer available, and if there was, the cost would be $900. I asked this local dealer about the Fasco blowers I learned about on the internet and shared with him the websites I found. The dealer suggested using the Fasco inducer and drilling the drain hole needed.

The old inducer on the furnace now was replaced 12 years ago with the Fasco 7162-3136 inducer. Like #Carrierman said before, correct me if I misquote, this replacement of the inducer 12 years ago may not of been done with the correct inducer.

When an HVAC guy was out about three years ago to correct a pressure switch issue (the hose was looped downward and filled with condensation) he said that our furnace was a "white elephant" that occurs numerous problems and will probably have to be replaced in the next couple years. I also believe that #Carrierman said that our furnace was actually a "Bryant"...related to the Carrier line.

I kinda figure that we will be replacing this furnace in the near future and are now starting our research in finding the best furnace that will fit our needs.

Seems my options are limited...

I agree, and i see some significant rust in the pictures you posted. I think the time has come to scrap out the "white elphant". I highly suggest that you look at Lennox......the quality control they have is second to no one. And the warrentys are very good as well on the higher end equiptment. The G61mvp is an awesome two stage furnace with a DC variable speed motor. Good luck in whatever you chose to do.

Hi casey

It looks like to me that they removed the nipple location on the replacement. If you still have the old inducer housing you may be able to use the motor mount portion on the new inducer. I am not quite sure why they removed the extra port on this casting. My guess is it saved them about .00002 cents to not add it. I am sorry they did this to you. And I hope I don't make acefurnacefixer mad at me. But if you replace a Carrier with a Lennox you will be sorry. We also are a Lennox dealer. We have had so many problems with them, the only ones we have left in our building are on the showroom floor. Lennox quality has gone to crap since they went national. I dont even consider them compairable to a Goodman.

Good luck
Rusty

I hear ya #Carrierman. I was thinking the same thing of swapping the cover from my old inducer with the new one. Aside from the drain location, lets just take that out of the equation for this conversation, what is the difference between the A142 and the A147? I have a feeling there is not. I also thought about the saving costs regarding this.

You've got to be kidding me...............Have you ever been to the manufacturing facility? Obviously not..........go there and see 1st hand the level of quality control they place into EVERY piece of equiptment that leaves the building. They also have a very low tolerence on failed parts from there outsoursers. I am telling you they are second to no one. Go there take the tour then come back here and tell me that .
