If your Kenmore gas stove burner is not heating properly, the burner flame may not be changing from low to high as you turn the control knob. The most likely cause is a damaged or stripped burner control knob that cannot rotate the valve stem correctly. Inspect the knob for cracks, worn edges, or a loose fit, and replace it if needed. If the knob is intact but the flame remains low or does not respond to adjustment, the Kenmore surface burner valve may have a damaged or wobbly stem that is not regulating gas flow. A burner cap that is misplaced, warped, or damaged can also produce an uneven flame and cause a gas burner to heat poorly, so make sure the cap is seated correctly on the burner base while the cooktop is cool and turned off. Finally, cookware that is too large or too small for the burner can reduce cooking performance.

If a burner flame is not changing as expected when the surface burner valve control knob is turned from low to high, it's possible the burner valve stem is damaged and not actuating the valve appropriately. If the valve stem appears loose or wiggles you should replace the surface burner valve.
Since burner caps help distribute the gas evenly around the burner, a burner cap that is not positioned correctly on the burner base can cause the burner not to heat properly. Confirm the appliance is turned off and the stovetop is cool to the touch, then readjust the burner cap, if necessary, so it is seated properly on the burner base. If the cap is damaged or warped, the flame can be higher on one side than the other. Inspect the burner cap for damage; a damaged burner cap will likely need to be replaced.
