Universal Gas stove burner not heating properly
When a gas stove burner is not heating properly, start with the burner control knob, the most likely cause when the flame does not change from low to high as you turn the knob. A stripped or cracked knob may fail to rotate the valve stem, so inspect it for wear and replace it if needed. If the knob is working but the flame remains low, the surface burner valve may be damaged or loose and unable to regulate gas flow. A gas stove with a weak flame or a gas burner that is not heating up can also have a burner cap that is misaligned, warped, or damaged. Turn off the Universal gas stove and let the cooktop cool, then reseat the cap on the burner base. Finally, make sure the cookware matches the burner size. A pan that is too large or too small can reduce cooking performance even when the burner works correctly. Enter your model number to find the exact replacement control knob, surface burner valve, or burner cap for your specific range, stove, or oven.

02 - Universal 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.
Less Common
03 - Burner cap not on correctly
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.
Less Common
04 - Incorrect cookware size being used
For best cooking performance use a burner that is best suited for the size of cookware being used. Using cookware that is too small or too large for the burner is not recommended.
