The only reason for this problem is that you have a gas leak at any point of the gas carrying tube or junctions. This is a common problem and the solution is to find out the leak, repair it, and reassemble to use it again. This safety mechanism gets automatically activated and it is called the BYPASS. The procedure to make it new again is to turning all knobs off, turn on the gas supply in full, wait a couple of minutes and you'll see that there is a pressure building inside. After a minute or two, the grill will be ready for normal operation. Now turn on the burner and hit the ignitor. There'll be no problem lighting up the burner and you'll notice that the burner is providing 500 to 550 degrees Fahrenheit without any problem.
