Turn on Power and check status of Relay & Driving Circuit by checking followings according to load operation.

Check after disassembling connected to MAIN PCB CN30 &CN32
Because it is NTC TYPE Sensor, risistance decreases as temp increases

1. Measure resistance between CN30 

⑧

and 

⑨

for R-Sensor.

2. Measure resistance between CN30 

⑤

and 

④

for F-Sensor.

3. Measure resistance between CN30 

⑥

and 

④

for DEF-Sensor.

4. Measure resistance between CN30 

①

and 

④

for Ambient-Sensor.

5. Compare the above values with current temps of Sensoer locations and Part Spec in Manual and evalute 

them.
