Evaporator Temperature Sensor / Switch: Description and Operation
EVAPORATOR FIN SENSOR
The evaporator fin sensor can be replaced without having to remove the unit housing from the vehicle.
The evaporator fin sensor is located in the unit housing and placed in the evaporator fins. The sensor prevents evaporator freeze-up. This is done
by cycling the compressor clutch OFF when evaporator temperature drops below freezing point. It cycles ON when the evaporator temperature
rises above freezing point. The evaporator fin sensor uses a thermistor probe in a capillary tube. The tube is inserted between the evaporator fins in
the heater-A/C unit housing.
