    So I had an AC tech come look at my all in one outside unit. The blower was just barely bumping once every few seconds and stopping, he cut some wires swapped some wires and came back with the motor was bad. I ordered a new motor and installed it... Put the wires back the best I could and... Does the same thing! I checked power and my 24v side on the transformer was 90v! So I ordered another one and I still have the same problem! I noticed if I unplug the white wire from the motor the 24v side reads 24v... Im stumped here.
