Your zapper igniter is only to ignite one burner and that burner lights the other burner and so on. Follow the directions inside the left door and do it in the propper sequence and it should work as it suposed to.

After making sure your knobs are installed properly examine the full length of all burner tubes. You will be looking for areas of corrosion or damaged metal.

It depends on which model you have as there are numerous different designs going back decades. So please indicate the model, the location of the knob in question and posting a picture would also be handy.

Stephan, repeat what you did before. Except, this time leave the hose disconnected for 5 minutes, before reconnecting it. Also, open the tank valve VERY VERY SLOWLY (Slow motion, slow) until it's fully open. Then light the burner farthest from the tank first and set it on HIGH. If it lights and the flame height looks correct, light the remaining burners the same way. If all the burners lit and the flame heights appear normal, you solved the problem. ALWAYS, open the tank valve very, very slowly.

If the above didn't solve the problem, then you will need to replace the grill's Hose/Regulator Assembly. You can pick one up at any home center or hardware store that sells grills & accessories for about $30.00. Be sure to take the old one with you for comparison purposes.

Hope this helped you and Happy Grilling!!
