My Weber Genesis Silver Grill seems to have a gas leak which resulted in a flames shooting outfrom under the middle burner control knob which melted that control knob so now I Can't use that control at all. Front and rear burners still ignite but auto ignition switch/button won't work either(it is stuck in the down position/ won't pop back up when you push it and doesn't ignite)

SOURCE: low/weak flame on Weber Genesis Silver B Grill.

hi my name is mark, could be one of two things the regulator on the propane tank try gently tapping on regulator it could be sticking, and make sure the vent on regulator does not have a spiders web . or the orifices to the burners are restricted. check regulator some are ajustable, some are not. hope that helps. thanks for your question.

SOURCE: Weber - Igniting the three grill burners (front, middle, rear)

it need a clean

SOURCE: Problem with gas getting to the front burner

Follow manufacturer's recommendation in resetting the excess flow safety device....(Turn burners and LP cylinder off...Disconnect regulator on cylinder. Turn both knobs to high for at least one minute...Then turn them to off...reconnect the regulator to the LP tank...Turn LP valve VERY slowly (30 seconds) until fully opened..then start the grill in the usual manner. ALWAYS TURN THE LP TANK OFF WHEN DONE USING THE GRILL....

SOURCE: Back burner won't light on my Weber Genesis Silver A Gas Grill

Only front burner lights (out of three) and it only has flame comming out of half of the tube.

SOURCE: I have a 2005 Weber

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!!
