Changing condenser fan motor.
I am a new building maint. student. What I would like to do is change out a condenser fan motor. I bought the motor and it has 4 wires and a new cap. Do I change the new cap I just put on the unit with the one with the motor ?
That's a tough call for this site, since none of us can tell what you have been taught as a student, what the school involved in known for teaching, or how much oversight you are being given.
You see, we avoid counseling potential DIY situations.
I can tell you this:
with every PSC motor I install, the correct value capacitor is always installed with it.

Always change the cap when a new motor is installed.
And make sure the fan is going in the right direction before you call it done!

with the sucky capacitors on the market today if they test good and look good most times i will leave them as long as they are the right size.
Helping a student with anything electrical can be dangerous!
Get you instructor to help
also agree with t527ed
Get er Done!
Do what has to be done
when it has to be done
as well as it has to be done
And doing it all the time.
When you put 'er in, give 'er a spin!
Once you do find out how to wire it, always spin it by hand before starting it up to make sure the blades have enough clearance and that you don't cut any wires or copper pipes.
Old motor a 3 wire and the new one a 4? Easy to change
