Refrigerant Pressure Switch Inspection

Install the SST (gas charging set).
Disconnect the refrigerant pressure switch connector.
Verify the high-pressure side reading of the SST (manifold gauge) and continuity between the refrigerant pressure switch terminals.
- If there is any malfunction, replace the refrigerant pressure switch.
