You can drop the motor, (two screws, and an electrical connector) and check it. (I won't say 'easily', as the back screw is fun to get to.)
+1, that back screw is a pain. I built a little doohicky to allow me to pull it out more easily, but I used a crosspoint screw when I reinstalled, on a flexshaft driver. My connector was broken, I found a good unit on a sojourn to the JY.

Oh, if you had the system refilled, pull the dust caps at the ports(you do have them, don't you?) The type of ports used have a tendency to **** a little when you have the system serviced, resulting in a slow freon leak(ask me how I know) A little bit of water in the port will tell you if it's leaking. If it is, just pop the inside with the end of a ball point cartridge and it should seal. be sure to install the caps again. They have a seal on them to give you a 2nd point of defense against a leak.
