Room Temperature Sensor: Inspection

INSPECT COOLER THERMISTOR (ROOM TEMPERATURE SENSOR)

Measure the resistance of the thermistor.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION CHART

Tester Connection	Condition Specified	Condition
1 - 2	25°C (77°F)	1.67 to 1.73 kΩ
1 - 2	40°C (104°F)	0.8 to 0.45 kΩ

If the result is not as specified, replace the thermistor.

HINT:

As the temperature increases, the resistance decreases.
