Refrigerant Pressure Sensor / Switch: Description and Operation
A/C Dual Pressure Switch (M/T)
To prevent compressor damage, the dual pressure switch will open if system pressure is too low or too high: below 176.5 ± 19.6 kPa (25.6 ± 2.8 psi) or
above 2943 ± 196.2 kPa (426.7 ± 28.4 psi).
A/C Triple Pressure Switch (A/T)
Low and high switch operation is the same as the dual pressure switch. The medium pressure switch will close when system pressure exceeds 1471.5 ±
98.1 kPa (213.3 ± 14.2 psi), turning on the condenser fan.
