Yes, I have a Jenn-air by Maytag --model SCE30600W. The bake/broil/convection relay board I think is out, due to a power surge . The burner is working, the rest is out. ; is there a fuse in it , or can you till me if it is ok to save.
If the control panel is blank and the only thing working is the stovetop then you would want to check for power from L1 to N on the control board. If there is 120 vac then the issue would be the clock assembly. If there is a display then you would want to check the high limit thermostat and if that checks ok then the relay board is bad.
