The pressure regulator on my Char Broil gas grill vibrates. I can put my hand on it and feel the vibration. This happens after I light the grill and increases in intensity as I turn the flame(s) up.I tried turning everything off ,disconnecting the connection to the LP tank and tapping on the regulator in case somethng was stuck inside. No help,when I relit the burners same thing happened. So I shut it down . Should I just replace the regulator?
