When your Frigidaire gas stove burner is not heating properly, the control knob is the most likely cause, especially if the flame does not change from low to high when you turn it. A cracked, worn, or stripped knob may not rotate the burner valve stem correctly. If the knob is intact but the flame remains low or does not respond, inspect the Frigidaire surface burner valve. A loose or wobbly valve stem can prevent the valve from opening and may require replacement. A burner cap that is out of position, warped, or damaged can also cause uneven heating, a low flame, or a flame that is higher on one side. With the gas stove turned off and the cooktop cool, make sure the cap sits correctly on the burner base. Finally, use cookware sized for the burner, since an oversized or undersized pan can affect cooking performance. These checks can help identify why your gas burner is not heating up.

01 - Frigidaire 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.

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.
