A/C REFRIGERANT TEMPERATURE SWITCH





1.
CAUTION:
Do not heat more than necessary.

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 2ohms or lower until the oil temperature reduces to 120°C (248°F) or less.
