Gas Range Control Panel Randomly Beeping

My Frigidaire Gas Range will randomly start beeping. There is no error code, and the only way to stop it is to shut off the breaker, and turn it back on. The control panel has been replaced twice luckily while still under warranty. Now after two years, it’s randomly beeping again. I can’t help, but think it’s really not a control panel problem. The oven works while it’s beeping, but the warming drawer will not function. I saw this video on youtube and wonder if it’s the right answer, but the guy says he changed out the thermistor in the warming drawer, and I can’t find this part. Here’s a link to the video, and any help would be much appreciated.

Thanks! :slight_smile:
