Need help finding specific capacitor!

Does that sound sensible?
Why do you want to replace what looks like a high end Amrad turbo cap with a low quality generic 50/5 -370 which likely comes from China or Mexico?

As long as the tech. doesn't come back for his expensive turbo cap then leave it in.

P.S. Also, I would never use a 370V cap. Always upgrade to 440v. Capacitor quality is the biggest component problem in the HVAC industry.

Because, once it was put in, the fan has run in reverse ever since.

It's not an Amrad - it's a motor-mate from motor-rundirect.com. Not that I think that makes any difference as I'm sure it's a decent quality cap.

Could just be a bad motor as was pointed out in post #3

I don't think the cap is causing reverse running. If it's bad I'd think the unit wouldn't start.

If you have a multimeter then do a basic test of the cap.

Try and get the manufacturers wiring diagram and double check everything.

Could be, but how can I ascertain that?

Process of elimination. Move the fan wire on he capacitor to one of the other 5 spots. Double check the fan wiring if you have not already. If both of those are correct then all that's left is the motor.

I understand that, but what I don't understand is why a motor going bad would run in reverse.
