[94 Armstrong HVAC] Doing routine blower motor replacement and ran in to issue
I picked up the recommended replacement blower motor and capacitor- the issue I have is that the old one didn’t have a white wire and there doesn’t seem to be a place to plug the white wire on the new one.
Red, black, and blue speed control wires are plugged in and the two brown wires are going to the capacitor. Green is connected to ground. The yellow wire is going from the capacitor to the board. White wire is hanging there with me nonplussed on seeing where it should connect to since the old motor didn’t have one and there isn’t an unattached white wire.
Thanks in advance!

Read the motor's label... It tells you what the wires all do, most of this stuff has instructions that come with it... White is mostly always neutral with most motor brands.. There should be two brown wires going to the capacitor. The yellow wire to the board you speak of is not a factory motor wire. It always helps to take pictures before you take something apart too.
I did read the motors diagram, the issue was that the board didn’t have a spot outlined for it. My HVAC buddy ended up getting back to me and the solution was wrapping the white wire with the yellow on to the same capacitor hole.
