Having trouble with top element on Kitchenaid KESS907SSS2 range. Continuity was good but replaced element anyway. Still would not heat. Switched wires with switch for good burner but would not work on that switch either so it is not the switch. All other elements work fine. Oven works fine. I need the schematic which I believe is in the tech sheet W10112097. Would appreciate any help. No apparent fuses but looking for a thermistor or relay or something else that could cause it.
