Barbecue fans blog

I have a three burner barbecue that is in good condition. Recently, when a third burner is turned on, the propane bottle (20 lb) makes an audible humming noise. If only two burners are used, no issue. If any third…noise and a mild vibration. It acts as if the draw for gas is too great. Level in tank is not the issue and I changed out the regulator without improvement. Any ideas?

David S asked:


When either lighting by match or ignition switch, barbecue will not light. Only after left on, covered does it build up enough pressure to light. Once lit, all the flame holes still don’t light or go out frequently.
