Trane / American Standard Model TWV024B140A1 Wiring Information
I have been looking everywhere I can think of and can't seem to find a wiring guide, diagram, or even simply a description. I just purchased a new blower motor for this air handler. Per the motor it has the following wires:
Cap 1
Cap 2
CC/CCW rotation wires (2)
L1
L2
Ground
It also has three different wires listed for L2 - a High, Med, and Low.
Does anyone know where I can find information on exactly where these wires go? Cap 1 and 2, rotation, and ground wires are pretty self explanatory and I can get those, but I have no idea where L1 and L2 go and which L2 to use.
There is also an option to hook this unit up with a three wire configuration, insulating one of the cap wires, hooking cap 2 to cap, hooking L1 to cap then to L1, then L2 to L2 via "speed tap" whatever that is. I think I would be better off wiring with a ground since that's the way the OEM was attached.
Any advisement?

Welcome to the forums.
The wiring diagram is posted right there in the air handler. It should be on the back of the blower door.
Did you mark where the original wires connected ?
There shouldn't be too much of a difference with the replacement motor.
Did you get the capacitor the new blower motor requires ?
