AC York Compressor Clutch Acting Up!!!

[Bill Green]

"I guess I wasn't clear... I meant under what conditions is it *supposed* to
turn itself off (like high engine temps?)."

 

It is designed to turn itself off when under-pressurized or
over-pressurized. Maybe you do not yet have enough R134a in system? Possibly
the pressure only rises enough when above 1500 rpm? Just a guess really.
Maybe you should buy or borrow a set of gauges to monitor the pressure as
you charge it.
