I have a Kenmore double gas oven/range that worked fine for about 4 years. Then last August the control board started going on the fritz, so I replaced it. It has worked fine since, but now I am getting some weird random beeping with no fault code.

The beeping is not steady, it sounds like Morse Code.

The oven still works, but I have to unplug it when not using it, and it drives me nuts.

My wife did note that it started doing it the other day after using the broiler, which she hasn't used in a long time. She has also been leaving the door shut when broiling. Could this over heat the oven?

Is the control board going bad again? Or could it be something else, like a temperature probe?
