Ordered four new knobs. Because of the stove model, the four knobs are three different parts. Three of the knobs fit and work fine. The fourth knob had the information printed on it, off by 180 degrees (in positioning, not temp). Hence, if the knob fit correctly, it pointed to the floor when in the off position. Yet, when turned to the off position-toward the ceiling, the flame was pretty high. The other three point to the ceiling. No flame. New knob being sent. Holding my breath.
