Hey Elvis,
When you say "cycling" over and over, is the compressor trying to start and you hear a "click" about every 5 or 10 seconds? If so, that's the overload kicking out. You may try a 3 in 1 start capacitor. I think you can get one at W W Granger. Try that. If the unit still won't start, the compressor is probably shot.
'> The other thing is check to make sure that all the wiring is good and tight. Good luck! Post back.
