My Repair & Advice
This repair was likely compounded by a second failed component after several unplug attempts.
The first failure occurred after the freezer door had been left ajar. The freezer temp wouldn't drop but inside it still felt cold. I did several panel resets and the 'unplug for 12 hours' trick, neither changed indications. Checking behind the condenser cover revealed that it was still cold and appeared to be function, but the evap fan did not appear to be working. At some point during one of the unplug resets, I believe the refrigerator defrost sensor died which complicated the issue as it would freeze the water tank on the fridge side.
Replacing the evaporator motor ended up fixing the freezer issue (you can usually check this by opening the door and holding the freezer shut button - if you don't hear anything the motor is probably dead).
After the freezer was working I had to let the fridge side thaw again before replacing the defrost sensor. Replacing defrost sensor fixed the water tank freezing issue.
Temperature sensor for freezer was not needed.
With both parts in, the whole thing is back to normal and working perfectly. One note of caution for those replacing evap motors, the connectors/pins can get kind of weak after 10 years of being in use. Some of the pins on the evap motor broke when I removed the connector which required some delicate repair work. That harness is no longer available and the pin style is very unique.
