Lenox inducter motor
 
I was hearing a louder than normal sound and it was coming from a top motor. I called a service company and they said it was the inducer motor. It's a 2002 model. Is this an easy fix for a DIY? Also how could I find the correct part number? Thanks

It's not too bad for a DIY. There's 4 screws that hold it in place and a screw down clamp on the outelt going to the flue. The wires connect through a plug. Remove the screws & loosen the clamp. Disconnect the wiring plug & unscrew the ground wire from the case.

Now you should be able to remove the old motor. There will I beleive be a gasket in the new motor, install it over the hole for the motor inlet in the furnace. Now from my experience with Lennox (I work at a Lennox dealer so I deal with them a lot) your new motor will come with a series of colored plastic rings to make that motor work for several different furnaces. Check your instructions to verify which color goes with your model furnace, then the ring simply pops in the inlet hole for the new motor.

Now simply put the motor back in place, resecure the screws & reconnect the flue with the hose clamp. Rescrew the ground wire, reconnect the power plug & you're set.

As far as the part give me your full model/serial number & I'd be glad to get you the part number.

Depends on how mechanically skilled you are. Sounds like a mid efficiency furnace, probably a G50 if he says 'top' motor as the highs are down lower. Post the model # here. If it is a G50 or G41 they are not easy to change unless you have good mech skills. several gaskets and an orifice plate need to be but together at once and removing the adaptor to the vent pipe can be difficult so beware.

Those numbers don't seem right. The C33 is your coil, the numbers you list for your furnace don't show as good numbers on Lennox's website. Usually lennox gas furnaces model numbers are G then a number like yuri mentioned above. The serial numbers should be numbers in the first four spaces. The first 2 numbers are the code of the factory the unit was made, the 3rd & 4th numbers are then year the unit was manufactured.

So your serial number should start something like 5902 assuming it is an '02 unit and it was made in the Iowa factory (most in my area are, yours may be different)

Got it G40UH-60C-110-04.

you say it is a G40 in your reason to edit statement. same as the G50 I mentioned earlier. mid efficiency furnace and not that easy to change the ventor/exhaust fan but Good Luck.

After looking up the parts I find this note attached to the needed part.

Quote:

G40UH/G50UH Refer to Service and Application Note H-06-4 for further details. For repair parts on G40/50UH -14 and earlier, a new side port inducer has been developed. For replacement select 24W95 replacement CAI kit along with the proper pressure switch. Select the proper pressure switch by verifying elevation. Once converted to the new side-port design, please select individual part needed. *Select 24W97 for 0 - 7500 ft *Select 56L32 for 7501 - 10,000 ft
That tells me this motor will need some converting, so yeah this seems like it isn't going to be as easy as most inducer motors as yuri said. But it looks like you need a 24W95 inducer replacement kit as well as either a 24W97 or 56L32 pressure switch depending on your elevation.

And as yuri said good luck & read your directions carefully if you decide to tackle this.
