9-5) Temperature Sensor - Samsung RB1855SW Service Manual

Circuit Descriptions

9-5) Temperature Sensor

1) The sensor uses the characteristics of thermistor. If temperature goes higher, resistance goes
lower. On the contrary, if temperature goes lower, resistance goes higher.
2) MICOM input voltage is counted by sensor as follows.
R
TH
V = X Vcc
F
R + R
TH 301
3) For the resistance information on temperature and MICOM input voltage, please refer the
conversion table. (Page. 41)
( Air Sensor)
When Sensor is open
MICOM input "HIGH"
(V : 5V, R : Sensor reisitance)
CC TH
30
When sensor is cut off
MICOM input "LOW"
