Hi, I have a Rheem model RXQJ-A10J Heatpump/AC unit. I can't seem to find this model anywhere online. I'm pretty sure the compressor motor is starting to go bad, but I can't find parts. The unit starts up and the exhaust fan on top runs fine, but the other motor makes a loud buzzing noise until, what I believe is a power or heat overload, then shuts off. Also when it shuts off there is a burst of air that slowly goes away.

I wish I could afford to hire someone to come out, but I don't have 600 or 700 dollars to pay someone to put in a what I could buy for $100. My numbers are probably off on the part, but I won't know until I can find what part to replace. Any help I could get would be great. That is also assuming I can buy it since I am not licensed. I will list all the numbers I got from the system panel
