Refrigerant Pressure Sensor / Switch: Testing and Inspection
Dual Pressure Switch Test
Dual Pressure Switch Test
1. Remove the dual pressure switch connector and connect the high/low pressure side terminals located on the harness side as shown in the
illustration.
2. Install a gauge manifold to the high-pressure side service valve of the refrigerant line. (Refer to Performance Test.) See: Heating and Air
Conditioning/Testing and Inspection
3. When the high/low pressure sides of the dual pressure switch are at operating pressure (ON) and there is continuity between the respective
terminals, then the condition is normal. If there is no continuity, replace the switch.
