GE Oven not heating to desired temperature

I have a JGSP31GER slide-in gas range (18 years old?).
After pressing BAKE and waiting 5 seconds, the temperature
indicator reads 390 (when the oven is cold).
If I set the bake temperature to 505, the oven seems to work
fine. However, if I set the bake temperature to 375, it
indicates that the oven is already to temperature and never
comes on. If I set the bake temperature to 425, the oven
comes on for a few minutes and shuts off (apparently it
"thinks" it has reached the desired temperature).
If I adjust the temperature calibration +/- 35, it offsets
properly (however, I can't offset by 390!).
I have replaced the oven HSI (igniter) and temperature sensor.
The electronic controls all seem to work fine. I can go through
a complete (3-hour) self-cleaning cycle. If I disconnect the
sensor, the controller indicates "open" (F3).
I've ohmed out the sensors (new and old) and both seem
to be around 1000 ohm at room temperature.
The igniters glow bright orange and ignite the gas just fine.
The gas flow seems fine. The only problem that I can find
is that the temperature indicator shows the wrong temperature.
I've tried holding the RESET button while powering on but it
doesn't seem to reset anything. Is there a way to reset the
temperature indicator or control panel?

Hello ridgemcghee. Welcome to Gas Appliances topic and our Do-It-Yourself Web Site.

Only method I am aware off to reset the control board, etc. is to unplug the appliance from the electrical power. Wait a few minutes and then plug stove back into electrical power. May not reset anything based upon problem description.

Not likely is the control panel (panel with the buttons) cause of the problem. More likely the main control board or one of the components it is connected to or controls. Not an inexpensive item nor one that can be returned if it does not resolve the problem. May have to call a service agent or call GE's customer help line. But at the age of 18 years old, doubt they have service info.

Retail appliance parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers. Appliance part stores and dealers are listed in the phone book. Often times over the counter parts persons also work in the field serving appliance and have a solution they use to diagnose and know what part that is defective.
