I have a fan from an old Carrier heat pump and was wondering if I am able to wire it to beable to use it as a fan in my garage. The 3 wires coming from the motor are brown, white and black? If able, how would I wire it?

Fan is probably a 240V and probably requires capacitor.

Look at the fan and see if it is 120VAC. If so, you should be able to use the black and white. Make up a test lead from an old cordset, connect the wires and plug it in. Make sure the fan is anchored well. If it runs fine. If it trips the breaker, you may try brown and white. Look for a wiring diagram on the fan.

Thank you. I thought that may be the case.

I was mistaken - the white wire is actually yellow. I did see there was a diagram on the motor, blk being common and the other 2 connected to the capacitor. The plate had CAP 7.50/350. Is this the type of capicitor I need? If not, I assume I can look find the size needed by looking up the motor number on the net?

Almost all HVAC fans need a run capacitor no matter weather it is 115 volt or 220 volt. The person who mentioned the wiring diagram is correct look on the fan MOTOR or on the old furnace/a/c unit for a wiring diagram. If you try to run the motor without the proper value run capacitor you will destroy the motor. Good luck with keeping cool.

You are correct (7.5 MFD / 350 volts) is what you need. Wire as per the diagram on motor.
