Evaporator Temperature Sensor / Switch: Testing and Inspection






A/C THERMOSTAT TEST PROCEDURE
- Connect battery power to the C terminal and ground the B terminal, and connect a test light between the A and C terminals.

NOTE: Use a 12 V, 3W - 18W test light.

- Dip the A/C thermostat into a cup filled with ice water, and check the test light.
- The light should go off at 36 - 39°F (2 - 4°C) or less, and should come on at 39 - 41°F (4 - 5°C) or more.
- If the light doesn't come on and go off as specified, replace the A/C thermostat.
