one of my burners has stopped working properly. It doesnt light when i push the ignite button but will if i put a match to it. the other problem with that burner is that when it is on a small amount of flames come out of the handle circled in the pic below. also, i noticed today that the burner itself jiggles a bit and the others dont. Is the burner done or is it something that can be fixed? Thanks for any help
