I started working on this because of a no ice complaint but saw that the vents were all blocked more or less with ice/frost. Removed the back panels and found ice all the way up to the area of the fan, defrosted and reassembled but realized the fan was not distributing any air and both compartments were staying warm. Removed panels again, evaporator was already frosty and tried to test fan but it is a 12v brushless motor w/3 wires, red, black, and white. Tried applying 12v to all combinations of wires but nothing happened, from what I read brushless motors are a different animal and require a controller to run, so I am not sure how test. I have a new motor that I am putting tomorrow but fear that it could be something else ( control board ).
Any help advice would be greatly appreciated.

UPDATE
As I mentioned I had the fan motor and installed it before looking at any voltages at the control board and it corrected the issue. I am still curious if anyone knows of any way besides the process of elimination to verify that the motor is good or bad, i.e. checking board pin out voltage, if voltage good motor must be bad. Is there a direct test for the motor, because there seemed to be similar ohm readings on both the old and new motors.
In any case thanks for any help.
