Not enough gas/flame.

It sounds like something got disconnected between your gas line and your venturi (which deliver gas to your burners. Take out the grills and whatever holds your rocks or ceramic briquettes and look at the connection where the flame is coming from. It may be obvious what has come apart, and the fix may be as simple as pushing it back together.

More than likely, the problem is with your grills LP Gas Regulator. To test this theory, tune the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow) until the valve is fully open. Now, light the burner farthest from the tank first and turn it to the highest setting. Has the flame height returned to normal? If so, light the remaining burners the same way. Do all the flame heights, now look normal? If so, you solved the problem.

If not remove the burners from the grill and clean the properly, as well as the venturi valve (part of the burner, where the burner orifice enters the burner) on each burner. As spiders like to go into them and build a nest. After a thorough cleaning, reinstall the burners and try again.

If that still did not solve the problem, you need to replace the hose/regulator assembly. You can get one at any home center or hardware store that sells gas grills and accessories. Be sure to take you old one with you for comparison purposes.

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

Charcoal and grease build up can restrict even the best gas burners , my suggestion is to clean your gas burners with a burner tip tool . You can purchase these at Lowes or Menards . Here is a website for you to visit to get the ideal . http://www.metaltech.com.sa/victor/tips.htm

You problem could be or probably is with the regulator...not enough gas pressure...

Propane, LP, or Natural Gas Regulator Problems

heatman101

the burner could be blocked or the orffice try cleaning them

Look for spider webs in the venturi tubes, check the orfices or it could be faulty controls. Verify the tank working properly by trying on another grill.

May likely be low on propane or propane tank gate valve not opened far enough. Otherwise sounds like faulty regulator.

check thermo coupling., its purpose is to keep heat at flame area-helps keep flame lit,like a pilot light... clean it with a finger nail file LIGHTLY- or use sand paper LIGHTLY, just to clean surface..

Yellow is a "reducing" flame meaning low oxygen, whereas blue is an oxidizing flame. There is not enough air mixing with the gas. Clean out the pipes and free the air intake holes on the first stage of the burner assembly.

Hi,
The flame maybe not enough try to clean the gas nozzle at back potion of the oven , look for small wire to clean the clug by dust and rust , after cleaning test the flame , the burner will increase in flame .
