Hi Willy I just wanted to say thank you so much for putting this video together.
I was able to diagnose by putting the red and the yellow together to positive and white to negative that the fan doesnt indeed not work, I ordered a replacement Thank you !

Finally! A great an understandable video on testing a god-dame 9/12volt freezer fan motor.

Because the motor runs does not prove that it's good. This motor has 4 wires. 1 of them is DC power and 1 is DC ground. The 3rd wire is for sending an rpm signal to the control board and the 4th is for receiving a rpm command signal from the control board.
GE refrigerators with these 4 wire motors have a "liner protection mode" . If you leave the freezer door open for a few minutes the freezer fan motor comes on. If it comes on you know the fan motor and the control board are good. If the fan doesn't come on you have either a bad fan motor or a bad control board or BOTH . Bad fan motors can take out the control board. So if you have a bad fan motor but think you have a bad control board, you can blow the new board.

@GLCApplianceRepairs: In order to be sure that it is the main pcb board that's not sending power to the fan, will you please show us how to test it?
Thanks and I look forward to subscribing to your channel soon.

Thank you very much! It is very useful and help me to check that my new fan does work, so figured out:why change new fan, it still does not work.

May I know why you join the yellow and red wire?

Why did you put the red and yellow wires together?

Just did this test on a DC Frigidaire evap fan. Has a brown instead of white wire. Fan says 12 volts. The test worked. Now I only have to buy the overpriced P.O.S. main board.
