AC Fittings seal? on York '87 4kq compressor

[Ben Swann]

If I recall correctly, that is the low system pressure switch.  If system
pressure is to low, the switch will not pass current to clutch.

Anyway, sounds like you have a leak and when the system gets too low, it
won't operate because the switch doesn't have enough pressure.

That's what I recall - top of my head, so don't rely on this info, but
verify with the diagram and the manual.
