Sears Whirlpool gas oven

Model Number: 665.75844005
Brand: Sears Kenmore
Age: 6-10 years

I have a Kenmore oven with the temperature is about 50 degrees low. I did the programming for +30 degrees, no change. I replace the sensor, no change. By looking a various troubleshooting sites they say replace the control board. However, there are four different control boards. I cannot find out which one controls the oven temperature. Any guidance would be appreciated.

I can find two possibilities either display microcomputer board (WP8523666) or an auxiliary microcomputer board (8273535).
I cannot find any tech info on this unit so the board that the oven sensor plugs into is your best bet.

Unfortunately it looks like both these boards are obsolete.
