Replace control board for Trane XV95 furnace
Hello,
After lots of research, I bought a Trane's part # CNT5159 to replace the existing board on my Trane XV95 furnace. How do I know that the board was bad? Well, I have 2 XV95's, which had the same problem of randomly kicking in upon heat calls. A service company came and fixed 1 of the furnaces by replacing the board for $1200. I watched the whole thing and thought that I could do it myself.
So, I ordered the board for $400 and ....ran into a problem in which the new board does not have the CIR-H connector installed (see second picture (new board), middle of third row from top or first picture (old board), third cable connector from left).
Could someone advise what I should do now? Return the board and pay another $1200 to the serviceman? Skip the CIR-H connector altogether? Plug the cable that was connected to the CIR-H to a different connector?
Thank you much in advance for your time and expertise. I appreciate any help that I could get.

The diagram shows CIR H and CIR N as the high voltage connections to the indoor FAN.
These terminals are always Hot since your original board is for a variable speed fan motor.
You incorrectly bought a board for a 4 speed fan motor.
The important thing to remember when ordering a control board for a furnace is to use the model number of the furnace not the series. Do not use XV95 as your model number.
It is like using a trucks VIN number to order a fuel pump versus getting the part for a Ford F-150.

Found it. It's CNT06017, which is replaced by CNT06585.
I found CNT06017 listed as new on Ebay by a warehouse liquidator. Not sure if it's still good when it has never been used. Do they age over time?

No they don’t age on a shelf like they do when installed.
They usually ship in a static protecting bag, I hope your eBay part is still in this bag.
