When your Modern Maid gas stove burner is not heating properly, the most likely cause is a damaged or stripped control knob that cannot turn the burner valve from low to high. Inspect the knob for cracks, wear, or a loose fit, and replace it if it no longer rotates the valve stem correctly. If the knob is sound but the gas stove still has a low flame or weak flame, the surface burner valve may be damaged. A loose or wobbly valve stem indicates that the surface burner valve may need replacement. Next, check the burner cap. With the gas stove turned off and the cooktop cool, make sure the cap is seated correctly on the burner base. A misplaced, warped, or damaged burner cap can create an uneven flame and cause the gas burner not to heat up properly. Also confirm that your cookware matches the burner size, since an oversized or undersized pan can reduce cooking performance. Enter your Modern Maid gas stove model number to find the exact replacement control knob, surface burner valve, or burner cap for your appliance.
01 - Modern Maid Range/Stove/Oven Control Knob
If a burner flame is not changing as expected when the burner valve control knob is turned from low to high, it's possible the knob is stripped out or damaged and unable to rotate the valve stem. Inspect the knob for any cracks or wear and replace if necessary.

02 - Modern Maid Range/Stove/Oven Surface Burner Valve
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.
