RIGHT KNOB MELTED .WHY

Hi, Sorry but nobody wants to give bad news. There is a tube that comes from the control knob to the orifice that controls the amount of gas to the burners, my guess without being able to look at it is that the orifice broke at the connection to the tube and the flames are shooting back toward the knob. However it is possible that the venturi opening ( the screened part on the burner tube that sets on the orifice ) became dislodged. Either way you need to remove the grate, remove the burner assembly and then look ( under the cart from the back) at the tube and orifice for damage. You do not indicate how old any of this is and they do rust out. Parts are available but you have to determine if based on age and damage you want to replace any of it or all of it. If you inspect it and find something that you think you can fix you can get back to us for more help. If it is as simple as the dislodged tube and the parts are OK, reseat it and check it out. I wish you the best of Luck!
