Answer David, You need to remove the grates and burner caps, and unplug the power cord to the cook top. You need to check and make sure all the venturi openings on the burner base are clean and free of any debris, Look down the center opening and find the brass orifice, check and clean the orifice opening. And check and clean the underside of the burner cap. When the issue is isolated to one or two burners, That's where you need to start, and check. Thanks and Good Luck
