Joseph H Argyle , TX May 31, 2020 Broken fan switch part # no longer available. Be careful not to tighten or twist the small hex nut in the knob cylinder/housing with force. there is a very small plastic set tab that can be broken off easily. how do I know? The orientation of the switch "box" is horizontal instead of vertical. otherwise, this replacement part # works as expected. I couldn't get the switch to attach plate removed, and the switch removed, without removing the entire cooktop and removing the top glass burner cover. Not difficult, but time-consuming.
