Evaporator Temperature Sensor / Switch: Service and Repair

Evaporator Temperature Sensor Inspection

Evaporator Removal and Installation
1) Measure resistance between terminals of evaporator temperature sensor.
2) Check that the resistance decreases as temperature rises as shown.

If check result is not as specified, replace evaporator temperature sensor.

Evaporator temperature sensor resistance
0 °C (32 °F): 6.65 - 6.84 kohms
25 °C (77 °F): 2.00 - 2.14 kohms
