I replaced the thermistor earlier, but the code was still flashing. I noticed the heater terminals were charred and pretty well covered in carbon. So, I replaced the heater, the thermostat and thermal fuse and replaced the 3/8" spade terminals on the heater wires. (These are hard to find - most electrical spades terminals are .250. Also, I crimped and soldered these for a connection with the lowest resistance possible). After all that, the code still flashed! I let the explatives fly, calmed down, and ran the control board test. (This is done by pressing "more time" "less time" "more time" "less time" in succession.) The control board was passing all the tests, but the thermistor test, and the only thing is in this circuit is the thermistor, the wires, the connector to the control board, and some circuit on the control board that involves a few resistors and the "brain" chip. So, I checked the terminals at the thermistor, the wires up to the control board and the connector at the board. The control board connector was fairly dust encrusted, so I unplugged it, cleaned the control board terminals and sucked away all the lint and dust. Finally, I carefully removed earch crimp terminal from the Molex connector (the white female connector) and cleaned and bent them to yield a better connection to the terminals on the control board. I put it all back together, and thus far it is working fine.
