Evaporator Temperature Sensor / Switch: Locations

Heater/Evaporator Assembly

A Thermostatic switch cycles the A/C compressor clutch to keep the evaporator from freezing. The thermostat switch capillary tube is inserted into the
evaporator housing. If evaporator temperature falls below 32°F (0°C) the thermostat switch opens, A/C compressor clutch relay opens to disengage A/C
compressor clutch. This regulates the evaporator temperature between 30° to 40°.

-

Switch opens: 

-1.5°C to + 1.5°C  (28°F to 35°F).

-

Switch closes: 

+1.5°C to + 4.5°C  (35°F to 40°F).

-

Switch opening and closing points must occur with at least 2°C (3.6°F) difference.
