I have a Kitchenaid gas range with a power burner (KGRA806PSS01). Few days ago, the control knob for the power burner stopped working. On the knob, there are Off, Lite, High, Med, Low positions. Also, there are three simmer levels there. When I turn the knob, it stops right before Lite position. I can smell the gas released when I do this. All 3 other control knobs and burners work fine. I did clean up dusts after removing the knob. What could be wrong with this?
Sounds like you have that individual burner valve is sticking or broke. Here’s your parts
