E-stat
Controller
The E-stat controller is used to prevent the
evaporator core from freezing. The NTC probe
senses the temperature of the air as it passes
through the evaporator core. An electronic control
circuit interprets the change in resistance of the
thermistor to indicate when the evaporator core
is near freezing. The control circuit then provides
an output to disengage the compressor clutch,
allowing the evaporator core to warm. When the air
temperature of the evaporator core warms up, the
circuit reactivates the clutch allowing the evaporator
to cool.
