9.2 Malfunction of Temperature Sensor

Troubleshooting for 

temperature sensor

Is

the wiring terminal between the

temperature sensor and the controller

loosened or poorly contacted?

Insert the temperature

sensor tightly

yes

Is malfunction

eliminated

Is there short circuit due to trip-over of

the parts?

Make the parts upright

yes

Is malfunction

eliminated

Replace the mainboard 

with the same model.

End

no

no

Is the 

temperature sensor  normal according

to the Resistance

Table?

no

Replace it with a

temperature sensor

with the same model

no
