Lyle, I finally attacked my issue this morning. I am measuring 10K across the existing thermistor. While in there, I also took out about 50 lbs of lint (Ok, maybe not that much).
I've left the existing thermistor in place and will hold off checking the harness. My hope is that cleaning the thermal blanket off of the thermistor, fuse, etc. will allow them to cool properly and the problem goes away. If however it doesn't fix my problem, can you provide details about getting to the control board? I did try, but could not get inside.
