One side note:.

This is the second pump which has burst at the blue plastic seam in seven years.

This is a side-by-side frige with water and ice dispenser in the left freezer door. I first checked for possible water line freezing in the freezer door or in the water chiller area (behind the vegetable drawers) as described in e-articles I had read, but this did not appear to be the problem. I found two solenoid valve pairs; one that ... Read more routes dispenser or ice-maker water to the filter and the other that routes the water to the end device. I ran a couple of tests on the solenoid valves and found that the first inlet valve that sends water to the filter did not work, but the second valve that relays the water to the dispenser was still working. By temorarily connecting the wiring for the dispenser solenoid to the functioning ice-maker solenoid, I confirmed that the wiring and switch were working properly and that the problem must be the solenoid itself (it also still hummed when the dispenser button was pressed). The entire quad solenoid valve assembly can be pulled out after removing the one hex-screw on the back of the frige (the assembly is all held together with a bracket). I disconnected the wiring connector to the solenoid valves. I disconnected the plastic water tubing by pushing it toward the fitting and then depressing the tubing inlet ring to release the tubing. I removed the two screws holding the solenoid valve and replaced it.

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 ...

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.
