Replaced the controller that the temperature knob connects too. Discovered this on one of your videos, or I wouldn't have known what to change out. Works perfect now, and wife is really happy. She has been doing without it for almost a year. The stove also needed new drip pans and rings, which we could not locate locally. Found them on your website (perfect fit by-the-way) and that is what got me to looking for a solution to the other issue with the burner.
Many thanks for the video, and the parts.
