Hey, thanks for the response.
In this instance it was my Evaporator fan. As the compressor was working normally and the freezer and fresh food boxes were cold in the bottom (but not the top) it seemed to be a circulation issue.
Fairly straight forward to remove the back panel from the freezer box, the evaporator fan is right there (not working...), I pulled it and hooked power to it via an old extension cord. When it did not power up, I went and secured a replacement, installed it and 1.5 hrs later we are back at 0/34 degrees.
I was concerned it was the defrost timer or a relay that perhaps I couldn't easily trouble shoot, but thankfully it was straight forward.
I bought the fan motor locally, which I like to do, but paid $12 more than the on-line w/ shipping option.
But at the time getting the refrigerator running was priceless.
Hope this helps someone else out in the future.
Chris
