A/C Pressure Switch

The A/C pressure switch consists of a High-Low pressure switch (A/C pressure switch A) and a Middle pressure switch

(A/C pressure switch B).

High-Low pressure switch

If the refrigerant pressure becomes too high (due to blockage), or too low (due to leakage), the A/C pressure switch

sends a signal to the fan control unit to prevent the compressor from operating.

ON

OFF

• Middle pressure switch

If the refrigerant pressure goes above or below 1,520 kPa (15.5 kgf/cm2, 220 psi), the A/C pressure switch sends a signal

to the fan control unit to change the speed of the condenser fan and radiator fan (High-Low).
