Refrigerant Temperature Sensor: Testing and Inspection

REFRIGERANT TEMPERATURE SWITCH




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

CAUTION: Do not heat more than necessary.







2. When the oil temperature reaches the standard value, check the continuity between the terminals.

NOTE: When the oil temperature is 150 °C (302 °F) or more and there is no continuity, the resistance will not be 2 Ohms or lower until the oil temperature reduces to 120 °C (248 °F) or less.
