* 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  and  for R-Sensor.
2. Measure resistance between CN30
 and  for F-Sensor.
3. Measure resistance between CN30
 and  for R Defrost Sensor.
4. Measure resistance between CN30
 and  for F Defrost Sensor.
5. Measure resistance between CN31
 and  for Ambient Sensor.
6. Compare the above values with current temps of Sensor locations
(4-6.Temp Sensing Circuit Table)and Part Spec in Manual and evaluate them.
