Evaporator Temperature Sensor / Switch: Testing and Inspection

Evaporator Temperature Sensor Inspection:

1. Check resistance between sensor terminals as shown on image chart. Resistance decreases as temperature rises, and vice versa.
2. If not as specified, replace sensor.

TEMPERATURE RESISTANCE

32°F (0°C) 4.6 - 5.1K ohms
59°F (15°C) 2.1 - 2.6K ohms
