INSPECTION
PROCEDURE
1. INSPECT COOLER THERMISTOR (ROOM TEMPERATURE SENSOR)
(a) Check the resistance.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition |
Specified Condition |
I227-1 - I227-2 | 10°C (50°F) |
3.00 to 3.73 kΩ | I227-1 - I227-2 |
15°C (59°F) | 2.45 to 2.88 kΩ |
I227-1 - I227-2 | 20°C (68°F) |
1.95 to 2.30 kΩ | I227-1 - I227-2 |
25°C (77°F) | 1.60 to 1.80 kΩ |
I227-1 - I227-2 | 30°C (86°F) |
1.28 to 1.47 kΩ | I227-1 - I227-2 |
35°C (95°F) | 1.00 to 1.22 kΩ |
I227-1 - I227-2 | 40°C (104°F) |
0.80 to 1.00 kΩ | I227-1 - I227-2 |
45°C (113°F) | 0.65 to 0.85 kΩ |
I227-1 - I227-2 | 50°C (122°F) |
0.50 to 0.70 kΩ | I227-1 - I227-2 |
55°C (131°F) | 0.44 to 0.60 kΩ |
I227-1 - I227-2 | 60°C (140°F) |
0.36 to 0.50 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 thermistor (room temperature sensor). |
