I bought a GE true temp oven and the burners work fine. I started to try the broiler but its like the button didn't respond so I pressed bake and set a temp and it clicked and started heating up but a few seconds later the probe light started flashing and beeping so I could press the start button and it would silence for a few seconds but then it would start back beeping and flashing probe. There is no probe in the oven. But everything I've googled days it does that when there is a probe plugged in. Any ideas anyone? Thanks. Jon
