[sm=helpout.gif]The A/C is not cooling. You can hear when the compressor cranks up and then suddenly shuts down; it sounds like a "click-click" followed by another "click-click". It has presure, no leaks detected. Any idea of what is the problem? Also, I can see one of the presure/line valves but can't find the other???

 

The 850 only has a low pressure fitting for the A/C.Most of the time the compressor will cycle like that when the freon level is low.
