What type of A/C is it????????????
Lots of different types out there that have very different components in them.
Just a thought......... did they bench test the 'new' motor to be sure that it was operational? If the old one tested 'bad' , then test the new one to be certain that it is good before installing. Always a good practice, as I see a fair number of new replacement parts that are 'bad' out of the box!
