Check resistance between terminals.
Sensor Temperature (5C (5F))
If it is not within specification, replace thermistor.
NOTE:
When the thermistor is removed, its should be reinstalled in
original position.

DUAL PRESSURE SWITCH
INSPECTION
1) Check switches for continuity at normal temperature (approx.
255C (775F)) when A/C system has a proper charge of refriger-
ant and when A/C system (compressor) is under operation. In
each of these cases, switches should show proper continuity.
2) When pressure is following specified pressure, switch should
show no continuity.
