Evaporator Temperature Sensor / Switch: Description and Operation
EVAPORATOR PROBE
The evaporator probe is located in the HVAC unit housing and inserted into the evaporator fins. The evaporator probe uses a thermistor probe in a
capillary tube. The probe prevents evaporator freeze-up.
As the temperature of the evaporator increases, the resistance of the sensor decreases. As the resistance of the sensor changes, the voltage
monitored by the Control Module also changes. The monitored voltage indicates to the Control Module the temperature of the evaporator.
