Same thing happened with mine except it wasn't the element but the control module which had a burnt out track which controlled the heating element. Unscrew the door panel, remove the module open it up and you will see burnt out track. Solder a wire onto the track to bridge burnt out section and it should work again. Alternatively it could be the heating element and like you I haven't been able to locate it. The burnt out track is a known weak point on the SB925 so check this out. Good Luck
