Ghost of a model with no info from Sears or reliable parts lookup. Needs a new control board since it keeps overheating and blowing the blower thermostat, despite seemingly good airflow. I should've photographed the old control board when I had the chance as it's a nightmare stacked in a cubby hole installation.

Uploaded service manual pending approval: 

Here is the control module number, be sure to check the temp thermistors.

Thank you, I believe the issue is in the main control board though, not the display control board. I figure that there just be a contactor stuck closed. I used  AGM30045804 kit and swapped out all the thermal fuses and thermistor even though it was just 6931EL3002M that failed on the blower housing. Turned it back on and it burned non stop til it tripped again. Gas valve could be sticking I guess but I think it's more likely the board contactor is stuck closed based on my research about LG continually burning out the thermals with ok ventilation.

You are correct, missed it. Bad news there is 3 to choose from in the exploded view.

Oh my, that's a real drag. Is there a method to find out which one or just have to see if I can find the info on the old board?

[Vance R]

About 50% of the time there is a service bulletin to help, but in this case no bulletin.  None of the boards sub to another one at encompass.
