3% per degree centigrade. Sensor used in the refrigerator is NTC thermistor.
There is following computing formula for the sensor:
Sampling voltage / reference voltage = R1 / (RNTC + R1)
AD value / reference AD value = R1 / (RNTC + R1)
The reference voltage is 5V, RNTC is the resistance value of the sensor, R1 is R31\R32\R33 in
schematic diagram that is 5.1K
10.4
Fan motor circuit of the freezing chamber
The fan in the freezing chamber is running when the compressor is operating. Check 12V and
FAN to see if there is a voltage of 12V. When in normal operation, the fan is in low level and the
voltage between 12V and FAN is more than 11V. If there’s no voltage when the compressor is in
operation, fan motor or electric control panel can be replaced.
