Thanks for all the info. that you have posted. Its is making it more clear.
I checked the Refrigirator Thermister value with various temperature and I got the following:
Temp. Ohms Read Ohms per chart
0 12K 22.7K
40 3.5K 7K
60 2.5K 4.1K
Could this be the problem? Also when I measure voltage in Step 5 (Air Baffle Motor test) (between white and Black) of the diagnostics, where can I find the white wire?
