Evaporator Temperature Sensor / Switch: Testing and Inspection

INSPECT EVAPORATOR TEMPERATURE SENSOR
Inspect evaporator temperature sensor resistance.




1. Place the sensor in cold water, and while changing the temperature of the water, measure resistance at the connector and at the same time, measure temperature of the water with a thermometer.




2. Compare the 2 readings on the chart.
If resistance value is not as specified, replace the sensor.
