Strip it down behind the knob and the venturi tube. You have spiders nests back there and the flame is pooling there instead of firing down the venturi tube to the burner. The venturi mixes air with the gas.
More than likely, the venturi valve is clogged by a spider or spider web. You will need to remove the burner to check for this and clear them out. The venturi is the part of the burner that fits over the burner orifice. It may be 2 slots cut into both sides of the burner tube or a series small holes that are not burner port holes.
Hope this helps you and thanks for choosing FixYa. Cheers...
Jeanne - Did you remove the burner to clean? If not. you weren't able to clean the Venturi Valve, which is part of the burner. Spiders love to get in the Venturi Valve & build a nest. When that happens it stops the gas to that burner. I suspect, that may be the problem. The Venturi Valve, is part of the burner (the open end part) that's closest to you, when you face the front of the grill. It will look like 2 slots (one on each side) cut out of the burner tube, where it fits over the burner orifice. But, you can't see it, without removing the burner. An old tooth brush works well to clean it.
Hope this helped you to solve the problem. Please let me know and Happy Grilling!!
If you remove the burners, the Venturi Tube is part of the open end of the burner that fits over the burner orifice. It should look like a slot on each side of the burner. There's really nothing to open, once the burner is removed.
The venturi tubes are part of the burner. It"s a slot on both sides of the burner tube, where it goes over the burner orifice. You will need to remove the burners to check and clean them.
I think you husband is trying to clean the wrong thin. The venturi tube is part of the burner itself. It's the open end of the burner, that has an air intake adjustment on it. It fits over the burner orifice. He may be hitting the orifice, which in fact may be clogged. Remove the offending burners and he will be able to see the burner orifice, which can be removed with the appropriately sized wrench. Once removed try blowing through it. If air doesn't blow through, it's clogged. Clean it with a straight pin that is no larger that the orifice hole. You do not want to enlarge it. Also, the new burners may need adjustment of the venturi for the proper air to gas mixture. Consult you Owners Manual on how to adjust it.
Hello- You got lucky and only have one stuck, unfortunately you will need to order a few more parts. The only way to get the venturi out is to drill it off, drill it down enough that you can get the burner around what use to be the nut portion of the venturi. You will also need to get the orifice holder that the ventrui screws into under the cooktop. These parts are pretty cheap. You could try to put some LIquid Wrench around the ventrui overnight but be sure not to try to force it out too much because the gas supply tube to that burner can get creased if the orifice holder starts to turn...
What works best for me to drill the venturi is a countersink, preferably for metal, which has it's largest diameter bigger than the outside of the venturi. Get some cutting oil and start drilling, the ventrui's cut pretty easily but take your time and try not to damage the burner. Once you get down real close to the burner you can try to carefully pry the burner over the remnants of the venturi. Good luck, hope this helps. Best regards.
Can you see the smoke coming from the tip of the flame itself? Did you not have this problem before you replaced the burners? If yes to both, then the problem is with the venturi tube of the burner not providing enough air. The venturi tube is the part of the tube where the gas jet from the valve first enters it. There are some holes that control the air/gas mix by their configuration and size. Perhaps you have the wrong model replacement burner. The orifice (very small hole) out of which the gas shoots into the venturi, and the venturi tube itself are both designed slightly differently for use with Propane (bottled) or Natural (piped) gas. Perhaps your new burner has an adjustable venturi to allow more air. If so, remove the rocks so that you can see the flame and adjust by trial and error.
Hello, You may have a rusted, clogged or
damaged burner or venturi tube. With a flashlight, check for spider
webs, wasp nests or dirt (mud) dauber nests in the opening of the
venturi tube where it connects at each gas valve orifice. Clean it out
manually or blow it out with air compressor. Make sure the air
adjustment opening (on the end of the burner's venturi tube) has not
been changed. If it's closed too much, it will be difficult to light and
cause lazy yellow flames. If it's not clogged, the burner may just be
old and rusted and the burner holes are not allowing very much gas
through anymore. It's also possible the burner has rusted so bad, the
burner holes have been enlarged, it is falling apart or has cracks along
the burner seams. If so, replace the burner(s) immediately. It is
unsafe to use. Your local propane co can usually order the parts you
need and some will even do the work, if you are uncomfortable doing it
yourself. Bring with you the Make, Model and Serial number of the grill,
so they can order the correct parts for your specific grill. Also
specify whether it's natural gas or
propane. Douglas
