Oven won't stay on saying f 3 - GE Profile Spectra JGBP90 Gas Kitchen Range

hay jerry , tech sheet says to change oven temperature sensor ,good luck APPLIANCES R EN

I have one that won't light at all, what could the problem be?

Switch is out of alignment.

Sounds like the control board is not communicating correctly with the rest of the unit, consult a professional.

The light may be loose, or one of the micro switches are going.

try replacing the door hinges

I would say a fuse in cuircit board or something in the mother board

The temp is controlled by electronics that monitor the oven sensor.
The sensor should ohm out at 1100 ohms.
If it is shirted to frame or open the open temp would not do right and the
oven control would not know what the temp was and would probably declare an F-3 error.
In your case I don't think that is the problem. What i think it is going to be is the ignitor. If it is getting weak it sometimes won't draw enough amps to open the safety bimetal inside the gas valve.
Probably the ignitor is on it's way out.

The oven won't come at all.

i would have to say that there would be a problem with the ignitor and control regulator
