Thermistor Fan
1. Function
• The fan senses the temperature of exhaust air.
• The higher the temperature is, the smaller the resistance is.
2. Specification
• Thermistor with following temperature-resistance characteristic.
at 90°C : R = 4.43 kΩ
at 40°C : R = 26.07 kΩ
• Type name : CWT-DWE-1C18-A
3. Checking method of mal-function
• If the resistance between terminals is within the adequate range, the fan is in
normal operation.
• You can test the resistance of the thermistor as follows.
- Put the metal rod into cold water (10~20°C): 40 within 30 seconds
- Put the metal rod into boiling water (95~100°C): 4 within 30 seconds
• If ‘H2’ error is displayed when you press the power and start button, the thermistor is not connected so
replace it.
