No these are a one time fail valve because the reason there is a flame is the packing has came out of the valve. Most of these valves may be purchased from either westlake hardware, home depot, or wal-mart.

Your Question Preview Fire Magic A790i Logo Problem with A790i Firemagic a790i flames pop and knobs get hot Posted by Author imageGuest on 3/24/2013 Details not getting good pressure to all 3 b


It sounds as if the burners may not be properly seated on the valves. Instead of all of the gas flowing into the burners, some of the gas is escaping behind the front panel and creating a fire behind the front panel which would heat the valve shafts and melt the knob inserts. This call also be caused by partially blocked burner venturi and valve orifices.

Check to make sure the end of each valve is completely inside of each burner.

I have a 3 knob grand gourmet grill with a newer burner, I light the grill with the first knob, turn on the second knob, turn on the third knob and the flame goes out, any suggestions?


To troubleshoot & solve this problem, first be sure you have adequate gas in the tank. If that checks out OK, do the following:

1. Turn the gas tank valve OFF and disconnect the hose from the tank.

2. Wait 5 minutes and reconnect the hose to the tank.

3. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).

4. Once the tank valve is fully open, light the burner farthest from the tank first and set the burner
control knob on HIGH. Does the flame height look correct for being set on HIGH? If so, light
the remaining burners the same way. Do all the burner flames look correct? If so, you solved
the problem. Remember, to always open the tank valve Very, Very Slowly.

If that didn't solve the problem, you will need to replace the grill's Hose/Regulator Assembly. It runs about $30.00 at any home center or hardware store that sells grills & accessories. If you replace it, turn the tank valve ON Very, Very Slowly.

Hope this helped you to troubleshoot and solve the problem. Happy Grilling!!

The problem lies with the grill's regulator and how the gas tank valve was opened.

Why do flames shoot out behind the control knob on my aussie gas grill


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...

BBQ won't get hot enough. What can I do? There is plenty of propane. Pete


I suspect the problem, is a result of either dirty and/or clogged burners and venturi valves (part of the burner). Or the grills gas regulator is partially locked close.

Since the regulator problem does not involve any real dismantling of the grill, I'll start with that solution first.

1. Turn the gas valve on the tank OFF. Remove the grill grates and flame tamers, so that you
clearly see all the burners.
2. Disconnect the hose from the tank and wait 5 minutes.
3, Reconnect the hose to the tank and turn the tank valve ON, VERY, VERY SLOWLY (Slow
Motion, slow).
4. Once he tank valve is fully open, light the burner farthest from the tank first and turn the burner
knob to HIGH. Dose the flame height look correct? If so, light the remaining burners the same
way, until are are lit and burning. Do all the flame heights look correct when set on HIGH? If so,
you solved the problem.

If the above did not solve the problem, you will need to replace the grill's Hose/Regulator Assembly. You can purchase one from any home center or hardware store that sells gas grills and accessories. They run about $30.00. Take you old one with you for comparison purposes.

Hope this helped you troubleshoot and solve the problem. Please let me know and Happy Grilling!!

Grill worked fine for almost a year but I recently used charcoal following the directions in the manual (and it worked great). However since using it (& it is long gone), if I turn grill on high,...


Kathleen, the ash and debris left from the charcoal clogged the burners and caused the flames to shoot back thru the venturi valves, which is causing the flames to reach the control knobs. For the most part. I would suspect that the control panel, the electronic ignition, control knobs, the gas manifold for the burners and the burners are now completely shot.

Now, you're at the stage of determining is it worth it, to replace all the parts (if you can find them) and repair the grill. Since you didn't mention who the manufacturer of the grill is and how long you've had it. I have no way to tell how much it's worth. But, if it were me, and the grill is at least 5 years old and it originally cost $600.00 or less, I'd seriously consider replacing the gas grill with a new one. And if you want to do some charcoal grilling, get a separate inexpensive charcoal grill and take good care of it. During the weekday evenings when you don;t have time for charcoal grill to preheat, use the gas grill. On weekends, use the charcoal grill if you like.

Hope this helped answer your question and ultimately help you make the right decision.

Viking grill burner is clogged and fire is shooting out of knob. How do I clean my grill from excessive grease.


Is it still under warranty? I'd call Viking or a qualified repairman to fix it. If your burners are clogged, the flames should be coming out the venturi tube and flaming towards the gas valve knob. If the flames are coming out of the gas valve itself, then it will need to be regreased. If the burners can be removed without too much trouble, soak them in the sink with hot water and dishwashing detergent. Be sure to remove the knobs, so no one turns the gas on without the burners connected. If it's difficult, call a repairman.

Flare behind temperature knobs on jenn-air gas grill


This seems to be a problem for most Jenn-Air users. The burners are defective, rusted or clogged and allowing the flame to "back up." You most likely have a melted electronic ignitor as well as gas valve damage. The new burners that I received this week for my model 720-0061-LP are 1/2 inch shorter than previous versions. Time will tell if this fixed the problem. I would call Nexgrill and get all new burners and inspect the gas valve area for damage. Since 2004, I am on my 5th set of burners, glad they were free since I have a lifetime warranty on my model.
