Stop.When you put the burners in you MUST make sure that they go OVER the gas line from the burner control valve.If not when you turn the burner to on you are just allowing propane into the open air and NOT thru the burner itself.
A faulty control valve is the only reason for that. What happens when you observe the flames at the burner as you turn the control? Small flame to large flame? One other thing you can check is the venturi tube, that is the part just after the knob and jet, and just before the burner. Often they get filled with spider nests.
