Room Temperature Sensor: Inspection

  1. INSPECT ROOM TEMPERATURE SENSOR 
    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance 

      STANDARD RESISTANCE SPECIFICATIONS

      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 122 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
      NOTE:
      • Hold the sensor only by its connector. Touching the sensor 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 resistance is not as specified, replace the room temperature sensor
