Okay, so I have determined that my ge refrigerator's condenser fan is not working and it has caused my freezer (which is set to 0 degrees) to run warm (15 degrees) and feel very hot to the touch between doors.

I have tested the supply voltage on the mother board and it was reading 13.6 which falls between the appropriate voltage (12-14 vdc). To test I put black on j2 pin 3 and red on j2 pin 8

I tested the condenser fan voltage as well but am getting the same 13.6 vdc. This is higher than the 12 vdc, 8 vdc, or 4 vdc. To test i put black on j2 pin 3 and red on j2 pin 5

Should I conclude that I need a new control board? If so, how difficult is it to put a new board in? THanks!
