Ok, the first result of 10k reads 50 degrees, the second result of 13.9k reads around 38 degrees, these are your fresh food thermistors. The third result 16.9k reads 30 degrees, and the final result of 44.8k reads around 0 degrees.
Remove J2 harness and check resistance between red pin 8 and white pin 3. What is the resistance there? If it is 1.5k to 3k we can move on to next step.
Check the resistance on J2-3 white wire to J2-4 yellow wire. Does the circuit read open?
Plug J2 back into board. Check voltage at white wire J2-3 to same J2-4 yellow wire. What is the DC voltage reading?
Answer all these questions and we'll have an answer most likely.
