Condenser Fan Motor WR84X10055

First, unplug the refrigerator. Next, remove the lower panel on the back of the refrigerator that covers the compressor, condenser and fan compartment. Looking at the refrigerator from the back, the condenser fan is at the lower right corner. There is no information about removing the fan motor, so it took a bit of study. It became obvious that the plastic fan venturi (panel with hole in it for fan blade) needed to be removed. There were two screws that held the venturi panel in place. After removing these screws the top half of the venturi panel could be bent down and pulled from the cabinet. Note that there are tabs and slots on the bottom of this panel that will need to be matched up when replacing the panel. Next the fan blade needed to be removed. This is done by pulling firmly on the balde and it separated from the motor shaft. The most difficult problem was to remove the motor from the motor bracket. There is very little room to remove the two phillips head screws from the front of the bracket, so I used a socket ratchet wrench with an adapter that would hold a phillips bit. This allowed me to remove the screws which were at a right angle to the wrench handle. It took quite a few incremental ratchet movements to remove each screw. After the screws were removed, the motor and wire could be removed by prying the plastic motor bracket apart. There is a insulated cover that is tie wrapped over the motor plug. This was removed and the plug was removed. The steps were reversed to install the new motor. Be sure the venturi panel is positioned correctly and that the fan blade is pushed firmly onto the motor shaft.

The most dificult was the diagnosis. The condenser fan was turning slowly and the entire compressor/coil unit was too hot to touch. Removing the rear cover panel and placing a small desk fan behind the refrigerator cooled the compressor coil unit and allowed the freezer to get back to the 1 degree F operating range. This made my wife happy because she could continue to use the refrigerator and was willing to put up with the fan noise.

The Part select recommendation page stated that the most common cause was a control board failure [which was ultimately true] but I orderd a control board, a compressor fan motor and a themostat to be able to fix it in one exercise. The parts took ~3 days to arrive and during this time the desk fan kept the freezer at correct operating temp.
Replacing the control board and repowering the refrigerator [ took 1 hour] immediatly brought the original compressor fan motor up to speed. However it took the unit another 2 hours to get back to the 1 degree operating condition. The temperature had risen from 1 degree to 4 degrees in the time the unit was powered down.
