- Refrigerant and setpoint
- Match the refrigerant and the OE part number so the cutout pressure matches the specification. The switch exists to stop the compressor before low charge starves it of oil.
- Location
- Confirm whether the switch sits on the receiver-drier, a high-side line or the low side. Thread and port style follow the location.
- Diagnose before buying
- An open low-pressure switch usually means low charge. Find and fix the leak first. A new switch will simply open again if the charge is low.
