Recently my double oven beeps, and displays PF when we didn't have a power failure. I hit cancel and it resets. It is happening several times a day at different hours. Does anyone know if this needs a control panel replacement and is it difficult to replace? The oven works fine when I use it, but I feel it is getting worse and something will finally break down.

Thanks in advance

Do they still sell the control board? If they do can i find a manuel on how to remove and replace?

Thank you
