I just replaced one of these fans yesterday on a 22522 model, bottom freezer. It is a 2 speed fan. If you run the refrigerator into test mode (hold express cooling, and freezer colder touchpad buttons together for 3 seconds refrigerator will go into test mode) you will get power to the fan on test 1. compressor will run, and you should get 120 volts AC to fan plug. Reason for three wires - 2 speed fan. If you're getting 120 between white (neutral ) and one of the other wires, you have a bad fan and must be replaced. To get out of test mode, you must do this (pushing pad buttons together ) twice to return refrigerator to run mode. test 2, by the way, tests defrost system.
