Sorry Karl. This is one of those things that are product specific, and I didn't want to explain it if nobody here has the need.

Anyway, I was having trouble with my stove because the thermocouple took a long time to get warm enough to ignite the flame. You could hold it as long as five minutes, and let go, and the flame would go out. You can imagine how frustrating that is. So I called force 10, and they suggested that I try holding it in without the knob on. That was the solution, I only had to hold it for a few seconds and then it would stay lit when I let go. Apparently the knob was designed so that it would bottom out against the chassis without the shaft being pushed in far enough, so the solution is to insert something into the knob so that it doesn't bottom out against the chassis. I used the snipped off end of a tie wrap.
