    Installed new condenser fan motor and is noisy... what could it be
    Installed new fan motor on AC condenser and it is noisy. Checked for any mechanical rattles or rubbing and found nothing. Replaced motor again with another new one, same problem. I have done AC work for over 30 years what am I missing. Also replaced capacitor twice.

    Also replaced capacitor twice.
    Check size of capacitor being used. Incorrect size capacitor can make motor noisy.

    Perhaps new motor requires different size cap than old.
