Question on compressors

Group
i'm new here with a Cavalier 64-G unit.
Its been on its side for 5 years out in the elements.
When i plug it in the light come on and the fan turns on the
compressor.. Thats it!
It has seen better days..
But i want to bring this old girl back to life.
What can i do to check into the cooling?? Also can i use the following type compressor in her?
Refrigeration Compressor R-12, High Back Pressure Compressor
4149 BTU, 115 Volts??
thanks

First get yourself a good size extension cord, that will handle at least 15 amps, now open it up & look down at the compressor area, follow the electrical cord that comes off of the compressor, one should go over to the condensor (compressors cooling) fan electric motor, the other one short one (pig tail) should  have a pulg on the end & goes into what looks like junction block, (this is where the thermostat controls the compressor) unplug it fro the junction block & plug it into the extension cord (this will now supply power only to the compressor directly, bypassing the themostat & other wiring in the juntion block) carfully place a gloved hand on the compressor & "feel" for it running, (because sometimes with a lot of noise around it's hard to hear it actully running without it's fan whirling around)
in case you're wondering why a gloved hand, A:the compressor won't be grounded & may present a shock hazard, B:if the compressors cooling fan should kick in, it may decide to "bite" you, besides, if you've be trying to start it, it may still be physically still Hot, (heat-wise) safety first!  :'>  this should help you trouble shoot it, & we can go from there...

it may only be "stuck" from sitting for so long...

Joe - search these forums on refrigeration and troubleshooting.  Two or three months ago there was a fairly long set of posts that expand on JohnieG's directions.

PS - welcome to the boards and good luck with your cavalier
