Diagnosing a Bad GE Board - Part 1: Fan Motors

Hi everyone! If this video saved you from having to call a service technician to repair your refrigerator, please consider becoming making a donation to my channel here: It is greatly appreciated and helps to provide more videos! Also, If you haven’t already done so, please be sure to subscribe to my channel so you can be notified of new videos on how to fix your GE Side-by-Side refrigerator. This video will be part 1 of a multi-part video series focusing in on how to diagnosing a failed GE control board when you have problems with either of your fan motors not running. Most of the GE side by side refrigerators are going to use either a WR55X10942, WR55X10942P, or some very close variant of this board. GE Control Board WR55x10942 WR60X10185: (4 wire with no sensor attached) OEM GE Part: Cheaper Aftermarket Replacement: WR60x10074 (4 wire with thermostat attached) OEM GE Part: Cheaper Aftermarket Replacement: If you have not found it already, you should have a wiring diagram tucked in to the temperature control box in the upper refrigerator section. This can be accessed by removing the two screws with a 1/4in nut driver. As it relates to the fans, common symptoms of a failed control board include: - Fans that will not run - Fans that pulse and will not maintain consistent speeds - Burned resistors on the main control board - No response from any of the components other than the lights inside the refrigerator Time Marks: 0:26sec - Location of control board 0:54sec - Unplug from power warning 1:10sec - Testing supply voltage to control board 2:00sec - How to turn on fan motors for testing - Entering Linear Protection Mode 2:22sec - J2 Plug identification and pin out order 3:03sec - Testing supply voltage of 12-14vdc to fan motors 4:48sec - Testing supply voltage to the fan motors 5:25sec - Testing supply voltage to the condenser motor 5:11sec - Unplug refrigerator from power and J2 plug removal 6:30sec - Testing fan motor circuits 7:28sec - J2 wire identification 7:44sec - Visual inspection of burned resistors 8:15sec - Wiring diagram and wire function for a 4-wire WR60x10185 evaporator fan motor 9:47sec - PWM Fan motor tachometer test (Blue Wire) Hz/Frequencty Test **Pulse WIDTH Modulation** Whoops. 11:10sec - Close Up of J2 connector and Recap 12:36sec - Please subscribe! :)
