I am replacing a GE indoor fan blower motor with an AO Smith motor (same specs, supposedly the replacement motor). The old GE motor had only two wires besides the ground wire (1 black, 1 yellow, & green ground wire) Both the yellow and black wires from the GE motor were attached to the capacitor; the black line wire from the ac unit was also attached to the capicitor along side the black wire from the GE motor. The GE motor also had an outside plug where the red and blue speed wires from the unit were attached. The New AO Smith motor has three wires for the speed (red, black, & blue). The AO motor also has two brown wires (one with a white stripe) for the capacitor and a yellow common line wire. Obviously the two brown wires from the AO motor are to be atached to the capacitor... but how do I connect the others? There are only to line voltage wires (red & black) from the unit; Where do I connect these to the new AO motor? Is the black line wire to be connected to the capacitor like before, if so, to which brown wire? Any help would be appreciated. Thanks JC:)

It should say on the side of the motor,, yes the brown and br/white go to capicitor
The instruction on side of motot should tell you the speed of each of the other 3 wires, I hope you got a new capicitor that matches the new motor,, if you didn`t it's a must

The correct capacitor came with the new motor; my question is about the wiring of the new motor versus the old... I now have the two brown wires from the new AO motor attached to the capacitor. There are now the three speed wire (red, blue,black), and 1 yellow wire. The air handler unit had only to wires leading to the blower; one is black and it was attached to the capacitor on the old set-up 'next to' the black wire leading 'from' the old motor and the other is red and it was attached to the outside female plug on the old motor. My question is where do I attach the black wire & red wire (from the ac unit) now to the new AO motor?; (1) is the black wire supposed to be attached to the capacitor like before (and if so, next to the brown wire with or without the white stripe?) (2) this leaves the 1 red wire from the handler--is this supposed to be connected to the same speed wire as before? (3) where is the yellow wire (common line) to be connected?
New motor looks like... same specs.. go to...
