PROCEDURE

1. INSPECT COOLER (ROOM TEMP. SENSOR) THERMISTOR

(a) Measure the resistance according to the value(s) in the table below. Standard Resistance: Click Location & Routing(K67) Click Connector(K67) Tester Connection Condition Specified Condition Result K67-1 - K67-2 10°C (50°F) 3.00 to 3.73 kΩ kΩ K67-1 - K67-2 15°C (59°F) 2.45 to 2.88 kΩ kΩ K67-1 - K67-2 20°C (68°F) 1.95 to 2.30 kΩ kΩ K67-1 - K67-2 25°C (77°F) 1.60 to 1.80 kΩ kΩ K67-1 - K67-2 30°C (86°F) 1.28 to 1.47 kΩ kΩ K67-1 - K67-2 35°C (95°F) 1.00 to 1.22 kΩ kΩ K67-1 - K67-2 40°C (104°F) 0.80 to 1.00 kΩ kΩ K67-1 - K67-2 45°C (113°F) 0.65 to 0.85 kΩ kΩ K67-1 - K67-2 50°C (122°F) 0.50 to 0.70 kΩ kΩ K67-1 - K67-2 55°C (131°F) 0.44 to 0.60 kΩ kΩ K67-1 - K67-2 60°C (140°F) 0.36 to 0.50 kΩ kΩ NOTICE: Hold the sensor only by its connector. Touching the sensing portion may change the resistance value. 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 result is not as specified, replace the cooler (room temp. sensor) thermistor.
