12-15  COLD WATER SENSOR DEFECT

Tr

ouble

   

    

    

Shooting

Pull out the sensor by removing heating insulation. 
(O-ring inside, check for leakage)

Faulty cold water temperature sensor cause malfunction of cold water and ice making.

- When open: reconnect it if disconnected, and replace the sensor if defected.
- When short: Replace the sensor

3

Check the cold water sensor by opening front upper 
panel.

- 3PIN : 5V, Signal, gND

- gND is connected to the bracket screw in order for 
the sensor to work properly.

gND for cold sensor is affixed into SUS bracket.

Cold Sensor
- left: sensor pole, right: gND
* Affix gND onto cold sensor fixed area.

Defects display when Coolant leakage and cold water
