Refrigerant Pressure Sensor / Switch: Testing and Inspection

REFRIGERANT PRESSURE SWITCH INSPECTION

1. Install the SST (gas charging set).
2. Disconnect the refrigerant pressure switch connector.










3. Verify the high-pressure side reading of the SST (manifold gauge) and continuously between the refrigerant pressure switch terminals B and C, A and D.
- If there is any malfunction, replace the refrigerant pressure switch.
