I will provide more information to narrow it down.
The fan is the one in the fridge, (W10799015B) the fan in the freezer and ice maker are working perfect.
The control board that was replaced is the one you mentioned (WPW10675033 )
I did a diagnostic yesterday and everything passed and was successful except for the fridge fan. It did not turn on.
Switches on the door are working because when pressed (or doors closed) it triggers the ice maker fan to turn on, it also passed the diagnositc.
Freezer is working, water dispenser, ice maker, LED ligts, and left drawer.
I can hear the compressor turning on.
there is frost near the fan and along the wires but when you leave the fridge door open it melts it a bit. The frost doesnt touch the fan.
I can spin the fan manually.
Its like the fan is not getting power. Is there a way I test the connectivity? I have a multimeter, but do not know how to use it.
