There are two differences between the working unit and the dead unit.

1. In the dead unit, the defrost temperature sensor has no resistance from DFT to ground while the working one has.
So I am...

I measured the resistance from terminal Y to C and from C to the Y that goes from inside in 200 Ohm scale. In both cases the meter show blank (with indicator 1, i.e., it cant measure, I think).
