A new motor and controller on ebay is $500 while used ones are about half the price.

A picture of the motor location would be helpful to determine the ease of changing the unit.

I replaced my variable speed blower motor about 3 years ago with an Evergreen unit which had an integrated module. If I recall, I could have bought the module separately but for just slightly more money, I got a new motor as well. It was roughly $300 through eBay.

My last furnace was a Lennox with VS, $800 for the DC module and $1000 for the motor. It failed at least a half dozen times, with a 10 yr warranty they took care of it. The first time it happened after the warranty expired I replaced it. A Lennox engineer actually came to my house to determine the problem, they said it was due to the ductwork modifications that the dealer did to install it. I refuse to have a VS now.

Here is a rebuilt one for $320 verses a new one for $500.

I would check with either one of these sellers to make sure your spec for motor and module will work with their offering. Sometimes the motor shaft length can be different.

Can you have the motor rebuilt locally? I've had it done with pool pump motors. Maybe a cheaper option.

Furnace model number?
Air conditioner model number?

I replace mine with an Evergreen unit from Amazon. I just looked up. I paid $265 with 2 day free shipping for my model. You will also need a puller to pull the turbine off the old blower.

For your particular situation, I'd probably stick with OEM parts.

Otherwise with some modifications (see notes), you could install an Evergreen 6005, 1/2 HP. 239.95

Notes:
* Not recommended by manufacture.
** I don't recommend it for a DIYer.

No matter which option you choose, make sure to select the proper speed taps, to allow for proper airflow for the hi/lo heat and cooling operations.

Buddy of mine that was in the A/C biz told me that, since my system is no longer under warranty, I should replace any parts with Trane parts. Might cost a little more, but it's worth the extra cost over American Standard. Blower wasn't working one morning when I got up, but thankfully it was only the capacitor, so no major repair cost yet. Buddy said a new install would run $6k - $8k depending on how crazy you wanted to get.

Very common for part numbers to get superseded.
AmStd/Trane is the same company. Like Chevy/GMC.

You can see (in the link below) the MOD2186 supersedes your part number D341314P04 and fits your furnace model AUD080R9V3K4.

You can see (in the links below) that both of these parts fit your furnace model AUD080R9V3K4.

Control https://www.repairclinic.com/P...315022?model=1150692

Since your going OEM, your speed settings will be the same. So as long as they was set correctly when installed, they should be correct. But you know how things go, when you assume the previous tech did things correctly.

It is recommended to change both the motor and control.

It's the complete package.
As I stated earlier, the manufacture does not recommend it and I don't recommend it for a DIYer.

The control being out of stock is why I listed the link from amazon.

Thanks for the update. It's not very often that we get 'the rest of the story'.
Glad to hear everything is up and running.
