DESCRIPTION AND OPERATION

A/C Pressure Cut-Off Switch

Single

An A/C pressure cut-off switch (19D594) is used on all vehicles with air conditioning to interrupt A/C compressor operation in the event of high system discharge pressures, which could result in a loss of refrigerant.

The A/C pressure cut-off switch is a single-function refrigerant switch. It controls compressor clutch operation. This switch cycles as follows:

Clutch out at 2965-3241 kPa (430-470 psi) increasing pressure.
Clutch in at 1586-2000 kPa (230-290 psi) decreasing pressure.

The A/C pressure cut-off switch is located in the discharge line between the A/C compressor (19703) and the A/C condenser core (19712).
