Refrigerant Pressure Sensor / Switch: Testing and Inspection
Dual Pressure Switch
1. Check dual pressure switch (1) on liquid pipe for continuity at normal temperature (approx. 25 °C (77 °F)) when A/C system has a proper charge
of refrigerant and when A/C system (compressor) is under operation. In each of these cases, switch should show proper continuity.
2. Using a manifold gauge set, check switch for operation at specified pressure as shown, refer to "PERFORMANCE DIAGNOSIS".
Dual pressure switch specification
