I removed back panel in the freezer and found lots of ice clogging up the air vents going to the refrigerator section, and ice clogging the drain line below the freezer evaporator. I de-iced it all, it took awhile to do, but it has to be done before the refrigerator will cool properly again.

I saw the evaporator fan wasn’t running in the freezer, so I removed the electrical connector from it and used my multimeter to see if it was getting 120 volts to it, and it was. So I replaced the evaporator fan motor and it started blowing cold air.

Here’s the evaporator fan motor for this model:
