1. INSPECT ROOM TEMPERATURE SENSOR (COOLER THERMISTOR)


    E117004E25

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		10°C (50°F)
    		3.00 to 3.73 kΩ
    1 - 2
    		15°C (59°F)
    		2.45 to 2.88 kΩ
    1 - 2
    		20°C (68°F)
    		1.95 to 2.30 kΩ
    1 - 2
    		25°C (77°F)
    		1.60 to 1.80 kΩ
    1 - 2
    		30°C (86°F)
    		1.28 to 1.47 kΩ
    1 - 2
    		35°C (95°F)
    		1.00 to 1.22 kΩ
    1 - 2
    		40°C (104°F)
    		0.80 to 1.00 kΩ
    1 - 2
    		45°C (113°F)
    		0.65 to 0.85 kΩ
    1 - 2
    		50°C (122°F)
    		0.50 to 0.70 kΩ
    1 - 2
    		55°C (131°F)
    		0.44 to 0.60 kΩ
    1 - 2
    		60°C (140°F)
    		0.36 to 0.50 kΩ

    NOTICE:
    1. Even slightly touching the sensor may change the resistance value. Be sure to hold the sensor connector.
    2. When measuring, the sensor temperature must be the same as the ambient temperature.

    HINT:
    As the temperature increases, the resistance decreases (see the graph).

    If the resistance is not as specified, replace the room temperature sensor.
