Refrigerant Temperature Sensor: Testing and Inspection

COMPRESSOR ASSEMBLY [Except RALLIART]

INSPECTION

A/C REFRIGERANT TEMPERATURE SWITCH

CAUTION: Do not heat more than necessary.







1. Dip the metal part of the A/C refrigerant temperature switch into engine oil and increase the oil temperature using a gas burner or similar.







2. When the oil temperature reaches the standard value, check that voltage is supplied between the terminals.

Standard value:







NOTE: When the oil temperature is 135 °C (275 °F) or more and there is no continuity, the resistance will not be 2D or lower until the oil temperature reduces to 120 °C (248 °F) or less.
