GE wall Oven JKP15BOA2BB Shut itself off

Most likely the oven ignitor is bad or weak.  You can look at it and see how it compares to the broil ignitor.  If you see a whitish color on the ignitor and if it doesn't fully glow then it needs to be replaced.

First look to see if the ignitor is coming on. Most common problem is the ignitor is weak or just bad. When the power is applied to the ignitor it glows and builds up resistance to open the gas valve then it lights. If the ignitor is weak or bad it will not build up enough resistance for gas to come into the burner. One sign of this would be a "woosh" sound when it trys to light. If the ignitor is coming on but not lighting it is most likely the ignitor is bad. Should have a full glow. Also, if the ignitor looks whiteish in color this is a sign of it going bad. You can compare to the broil ignitor to be sure. If the ignitor doesn't come on at all will need to see if you have power to the ignitor. Let me know what you find and let's solve it before you rate the solution.

Hello ,
Welcome to fixya.
I'm Huuum and happy to assist you,

You asked, is there anyway to bypass the oven lock or bypass the self cleaning mode to get oven working?

Why do you need to do this?

If the door lock is stuck in closed position and preventing you from using the range?
You may free this by following this procedure.

Threat it like an error code.

This can reset the system.
Turn the breaker off to cut the power for 5 minutes.
Then restart the breaker and try the range.

It's like rebooting your computer when its acting strange!
Usually it corrects most problems!.
Or they are sometimes just a glitch.

If this does not remedy the problem, then the lock switch itself is bad and if you think you can bypass it then you may as well change it. Same labor!!.
Let me know how it works out.

This happens every time I clean my oven. It overheats, shows the f2 light and BEEPS loudly. The only way to stop it is to turn the oven off at the breaker box, wait until it cools (usually 2-3 hours), flip the breaker back on and start the process all over again until the unit is clean. If it's not to dirty, sometimes it's easier to juat use Easy Off.
hope it helped
