XSS25GGPBCBB General Electric Refrigerator

This story starts with a GE side-by-side refrigerator that has always had wide temperature swings and a temperamental water dispenser. The ice maker was not making ice, and the built in digital thermometer showed it was running warm. I suspected that the heat exchanger was full of dust and so looked there. What I found was that the con ... Read more denser tank was hot to the touch and the fan wasn’t running. As an experiment, I aimed a fan at the it for a while I saw that the freezer temperature dropped back to normal.
.The fan is marked as 11.2 DC so I checked for voltage at the fan and found some. With three wires and no wiring diagram I wasn’t sure this answered all the questions, but hooking the fan to a 12 volt power supply didn’t get it to spin.
I priced parts at a couple websites before using partselect.com . They also have a good diagram to look at (Sears diagrams are really poor). I ordered the part with 2-day shipping; it arrived on time, was correct and fixed the problem.

I first shut off water flow to the fridge. Examination of the package (which was not exact in appearance to the original) demonstrated that the electrical connectors were well-insulated so I arrogantly and successfully proceded without disconnecting the power. My fridge is old enough that the model doesn't appear exactly on anyone's list ... Read more so I wasn't alarmed that it took an extra 10 minutes or so to noodle out how to adapt the slightly different inlet cowling and electrical cord with extension, but the device is pretty simple.
Soon I loosened the two mounting screws with a nut driver, used a screwdriver to pry away the plastic snap-in housing over the electrical socket on the fridge inner wall and pulled away the electrical plug. The original water fill tube remained in its cavity, ready for re-use.
The new unit's mounting points matched the original screw locations perfectly, as did the fill cowling - which on the replacement icemaker has two possible attachment points. The new unit's electrical connector required an extension pigtail to adapt to my socket, but it was included in the package. The extra cable posed a minor cosmetic issue because it hangs in the collection basket a bit, but that will soon be remedied with a tie wrap.
After the water was restored and an anxious wait of a few hours, we had well-formed ice cubes that weren't all stuck together and the stalactites haven't reappeared.

I unplugged the electrical connection. Then I removed the 2 screws holding the icemaker in place. I lifted out the old icemaker unit and put the new one in place. Then put the 2 screws back in and plugged in the new unit.

The icemaker started making ice very soon after turning the unit on.
