Thought I would post a follow-up...

When I set the timer to defrost and jumpered the freezer thermostat,
the heating element still did not heat up. Verified with my multimeter
that it was seeing voltage. Got a new OEM heating element (about $20
shipped from EBay) and now everything is working great.

Thanks for the info and help!

I did some exploratory surgery last night and found this to be the
case, everything was behind the false wall of the freezer section.
The problem was then readily apparent that the defrost is not working
properly - the evaporator stuff was completely buried in frost. I let
it defrost overnight, and I now see the defroster heater and the
defroster thermostat. Looking at my wiring diagram, I see where the
defroster control should be (top of fresh food section), so I'll start
doing the defrost troubleshooting outlined at the site you referenced.

Thanks for the tips, I think I may have proper refridgeration before
long!
