This slide in oven has started beeping once, then the oven shuts off, and the display goes blank. Turn on a surface burner and the display flashes 12:00 and you can reset the time and the oven can be reset to the proper temp and it continues to cook. Minutes, or hours later the same thing will happen again. I have replaced the EOC and the same problem continues to occur. Ohmed the oven sensor at 1082 at room temp. No error codes have ever been displayed. Any suggestions GREATLY appreciated.
