Gas Stove burner flames too high
If your gas stove flame is too high, the burner air mixture may be improperly adjusted, especially if the flame hisses or appears unusually large. Some burners have an adjustable air shutter near the orifice, although many newer gas stoves use fixed shutters. Next, check that the burner cap is seated flat and correctly on the burner base. A warped, damaged, or tilted cap can make the gas burner flame too high on one side. If every burner has a high flame, the range pressure regulator may be set incorrectly, adjusted for the wrong gas type, or failing. A qualified technician should inspect or replace the regulator. A wrong orifice, or an orifice drilled for the wrong fuel, can also cause excessive gas flow and a high flame. Check the installation instructions or parts diagram before replacing the burner orifice. These issues can cause gas stove flame adjustment problems and may leave a burner too hot, so shut off the appliance and let the stovetop cool before inspecting it. Enter your model number to find the exact pressure regulator, burner cap, or orifice for your gas stove.
01 - Burner Air Mixture Not Adjusted Properly
Some burners have an adjustable air shutter just before the orifice. If the air shutter is not adjusted properly, the flame will hiss from too much air or too little air will result in a lazy high flame. Most newer ranges have fixed air shutters that are not adjustable.

02 - Burner cap not on properly
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.
Common
03 - Range/Stove/Oven Pressure Regulator
A pressure regulator is needed on a gas range to keep the pressure constant. If the pressure regulator is not adjusted properly, or is set for the wrong type of gas, the flames can be too high. This will affect all the burners. If you suspect the regulator is bad or not adjusted properly it is best to have a qualified technician check, adjust, or replace the regulator if needed.

04 - Wrong Orifice Installed
To work properly all burners need the correct orifice for the type of gas that is being used. If the burner flame is too high, either the gas pressure is too high or the orifice is too large. Check the parts diagram or the installation instructions for the proper burner orifice.
Common
05 - Range/Stove/Oven Orifice
All orifices are drilled and numbered according to the size of the hole. If the wrong orifice was installed in a burner, the flame can be too high. Make sure the correct orifice is installed in the burner.
Less Common
06 - Range/Stove/Oven Surface Burner Cap
A surface burner cap needs to be seated flat on the burner base for the flame to be evenly distributed. If a burner cap is tilted, the flames will be higher on one side than the other. If the cap is damaged, it will need to be replaced.
