Narrowed down the problem
The fridge was not cool enough again yesterday. This time I put a thermometer is, and yes, it is running about ten degrees warmer than it should. The frost is also building back up.
This time I pulled out the manual, and I searched on line. The problem has to be either the defrost timer (not advancing), or the defrost element (failure). I'll run the diagnostic test tonight, after class. There is enough information available on-line that this might be a repair I could do myself. I'm not sure I want to, though. Sears will charge $75 to come out, then parts and labor. Not sure if Center Point would come out for this (not that my fridge is covered by Center Point).
It's a repairable problem. In the meantime I bought 70 pounds of ice and loaded it into the fridge. I have an actual ice box!
