Does the sound come from inside the oven cavity or more toward the control panel? Any sparking or arcing inside the oven cavity when the noise is present?

control panel
Expert:  Kelly replied 12 months ago.

Okay, good, that is repairable. Issues within the cavity are not. What you are hearing is likely a power relay on the board that is beginning to fail. I suspect replacing the power board will correct the issue you are having. Please allow me just a few minutes to prepare some information for you, thank you!

where is it located
Expert:  Kelly replied 12 months ago.

In the diagram at the link below, number E2 is the board with the relays on it that I believe will need to be replaced.

I forgot to tell you how to access it, sorry. Please allow me just a few minutes to prepare some information for you, thank you!

Expert:  Kelly replied 12 months ago.

Access is gained by removing the grille from above the door. Once it is removed, you will be able to remove the screw from the top of the control panel. Lift up on the panel and it will hinge down, allowing full access to replace that board.
