I replaced the capacitor on the outside condenser fan motor today. Old one had corroded contacts and the motor wouldn’t start unless I kicked it by hand. Replaced it with the same size capacitor (5 MFD, 440Volt) metal can run capacitor (GE brand). Motor is single speed, 3 wire (brown, yellow, black, with the yellow and black wires connected to the same terminal on the capacitor).
Now it starts fine, but it runs backwards!! It’s blowing air down into the case instead of straight up. ??
Any ideas? Wires were hooked back the same.
And yes, we are running the AC’s today! (south texas)

Somehow when you were replacing the cap you got the starter winding connections reversed.
You somehow reversed the start winding polarity when you did the wiring.
Switch the start winding lead and the capacitor lead that go to the line terminals. You apparently got leads 1 and 2 reversed on one or the other of the windings. The side of the cap makes no difference.
Yep, sure enough, the black wire was supposed to connect to the brown wire, not the yellow!! Blowing upward now. Thanks!!!!!!!!!!!!
