hoping someone can help me verify my wiring to a AC blower motor. I think I have it wired correctly, I followed pics I took before I swapped out the motor. According to the diagram on the motor, black is high, red low and purple to line. Low was not previously used, nor is it now. When I turn the ac on the outside compressor comes on but the blower mortor does not. Theres no reset switch that I could see and I think I have the wiring correct. Also I replaced the capacitor and I just plugged the two brown wires to it, I'm using polarity is not important and I can just plug the brown wires in any order to the capacitor, btw it's the same capacitor.

Thanks in advance for taking the time to help me.

    Are you sure it was the motor that was dead to begin with, not the capacitor? May 14, 2022 at 0:48

    So it was actually the capacitor but I had bought the blower motor, it's the same direct replacement. Now I have a new capacitor and motor, but when I turn on the ac only the outside unit comes on. Breaker for blower is on. I will need to got back in the attic but was wondering if someone noticed any issues with the wiring.

    It sounds like you wired it right are you sure that the contactor was not the problem?

Today I went into the hot attic looked at the wiring and the posted wiring diagram and noticed the black wire to the relay switch was on 2 when it should of been on terminal 1. Once I made that change it started working. I will post a picture below.enter image description here

  • It's always the simple things that get you. At least you had a before pic to compare to
