you always want to see a blue color flame. A gas flame appearing yellow or orange in color or behaving with pops of yellow or orange indicates an improper ratio of oxygen for combustion. Often this improper combustion is temporary and could be caused by dust particles or a dirty burner that needs cleaning.

A wavering, yellow flame on a normal gas burner indicates that the burner is out of adjustment or the air inlet is restricted. As a result, the burner may be producing excessive amounts of CO. Improper fuel-air mixture. Insufficient ventilation of combustion gases.

The danger of orange or yellow flames Orange or yellow flames, or sooty flames, means you could have incomplete combustion happening, which could lead to carbon monoxide buildup in your home. There might be an air-gas mixture problem, or a problem with the gas pressure to the appliance.

Orange flames indicate oxygen deficiency actually. You’re right that it’s not burning efficiently, but the cause is likely an obstruction in the path of the aspirator/inspirator. The same amount of fuel exits the burner, but it mixes with less atmosphere on the way out.

A yellow burner flame is a symptom that the burner is not getting enough air for complete combustion of the gas. Correcting this problem involves adjusting the burner’s air shutter to admit more air, something that an experienced do-it-yourselfer can do.

NOTE: If the flames are too high or low and you must adjust them, you may do so manually.

1. Light all surface burners.
2. Turn the knob on the burner being adjusted to Lo.
3. Remove the knob.
4. Insert a small, flat-blade screwdriver into the valve shaft.
5. Turn the valve to adjust the flame.
6. Replace the knob.

To replace the burner, cut the gas and power to the stove, remove the burner cap and use a screwdriver or hex driver to disconnect the burner base. Use the model number of your stove to determine which replacement igniter you should purchase, install the new part, and replace the burner base, cap and grate.

Soak the Parts Soak the burner heads and caps in a mixture of liquid dish soap and warm water for about 20 to 30 minutes. This will help loosen debris that is hardened on.

Soak the sealed burner base in vinegar or warm water and use a stiff brush to remove any debris. Finally, clean any remaining debris out of the burner holes with a toothpick, sewing needle or compressed air. Reinstall the burner, cover and the grill, and try igniting the burner once more.
