Carrier 38YCA condenser motor problems

He declared that he thought the new motor was the correct HP (1/4) but possibly too high RPM...new motor is 1075 and he thought the unit might need a 825 but couldn't tell us because we no longer have the original motor. He said that the vibration and noise from the outside unit sounded like the motor was too fast for the fan blades...I thought it sounded noisier after the original motor was replaced but I don't know anything about heat pumps so I shrugged it off. He said that the blade is true so he doesn't think that's the problem. He also said that the unit stopped vibrating/rattling when he cleaned the coils...he seemed to think this was significant. This seemed to be an issue with the repair man who replaced the motor so he left us with the task of finding out what the correct RPM for our unit.
After finding the specs for our unit online (we didn't get them when we bought the house) and found that the new motor is the correct RPM 1070/1100 so we're left with wondering why the unit quit working and why it has the vibration problem. Does anyone know why the unit stopped cooling suddenly?
Thank you from Louisiana!
