Replaced fan, thermistor that comes in harness and defrost thermistor. The fan is still not running. What else could it be?
Everything but the fan seems to be fine. I put in a temporary fan plugged into external 120V and the refrigerator cools fine like that.

If the evaporator motor stopped running, you most probably have a blown motherboard WR55X10942. Fortunately, the driver in the motherboard is a fail safe one and never blows out evaporator motors.

Richappy, thank you for your reply.
I have not been able to find the wiring diagram. Do you know if the evap motor wiring goes through anything, or does it go straight back to the controller board?

Remove the freezer back panel, you will see the motor. Lots of times you have to splice the new motor in.

I bought a new motor with the harness and thermistor. I have replaces them and the defrost thermistor. The fan still will not run.
I have setup a temporary fan and everything works fine with it in place. So it does not seem like a controller board to me. So I'm asking if there is anything else that could be causing the problem. Or does it have to be the controller board?

It has to be the motherboard as I stated above. There is always the possibility you have a wiring problem, but that is rare.
