Hit the web to see if a similar problem was already diagnosed. It was.
Started hitting the web for a new switch, Found Appliance Parts Pros, LOVED the diagnostic tools for determining parts, discovered my switch was really a "regulator-energy; -; 50".
Ordered it with confidence. It arrived quickly. Took a photo for reference of the back of my stove's switch panel area. Released old switch from panel with two screws, started swapping out wire for wire. Was a simple process. Loved it. PLUS, I cleaned out the floor underneath and behind the stove and that was OK as well. Loved it when I plugged it back in, the "on" light was off accurately. Very satisfying.
