A / C EVAPORATOR THERMISTOR
(EVAPORATOR TEMPERATURE SENSOR)
A thermistor is a temperature sensor to sense the temperature of
air discharged from evaporator. The electrical characteristic is
shown in the figure.
When temperature is lower than preset temperature, amplifier
makes magnet clutch turn off to prevent evaporator from frosting.
INSPECTION
Check resistance between A / C evaporator thermistor (1) termi-
nals.
If check results are as not specified, replace thermistor.
