GE Profile Double-Oven Malfunction

I am stunned as yet another of my GE profile appliances fail.
This is a GE Profile Double-Oven, installed in 2000, model # JT950WDA2WW.
As I fired up the self-cleaning cycle for the upper oven, it locked down the oven door and set the time to 4 hours. All was good until the oven clicked over to the 2 hour mark. Everything shut down and it's alarm claxton started sounding. The error message is "F2" and clearing it doesn't help. I've resorted to flipping the breaker.
Can someone please provide some assistance with why the oven shut down and how to prevent it from happening again? (Beyond not running the self-clean.)

Range - Oven Error, Fault or Function Codes "F2 For an unknown reason, the oven temperature has exceeded a preset threshold."
So basically the temp overshot and tripped the safety limit.
F and a number or letter flash in the display.
You have a function error code.
Press the CLEAR/OFF pad. Allow the oven to cool for one hour. Put the oven back into operation.
If the function code repeats.
Disconnect all power to the oven for at least 30 seconds and then reconnect power. If the function error code repeats, call for service.
