URGENT Help !!!


I bought a new electrical motor for my air conditioner. It is a D7909 FASCO model, but the old motor had four color wires: red, yellow, brown & black while the new motor has four color wires: black, white, brown, and brown with a white stripe. I am not sure how to match them up. Can somebody help me?

First of all, is the speed, rotation, voltage specs the same as the old motor?

I suspect that some of those wires connect to a capacitor. Is there a wiring diagram supplied with the new motor? Is there a wiring diagram for the AC unit?

I have a diagram for the AC unit, but it is attached to the unit and too old to detach it. But the red and black wires are connected to the fan thermostat, the yellow and brown are connected to the fan capacitor. The unit’s diagram shows that the motor is a condenser fan motor (2 speed) with O’Load. The new motor is a D7909 FASCO model.

Give us the motor voltage or voltages it can run on.
I have a NEMA single and dual voltage connection diagram and color assignment sheet in front of me.

Ps....one or two capacitors?

The D7909 is a 1/4 hp 1.8 amp 208/230 volt psc condensor motor.

Connect your black and white to T1 and T2 on the fan motor contactor (thats not the thermostat) connect the other two to the capacitor. Brown the same place as the existing brown and the brown/white where the yellow is.
