Jim for Model Number Thermador H48HQS When I turn the hood on, it runs at full speed, when I adjust the speed control it slows down, but not much, it is still running really fast. Do I need a new solid state fan speed control switch?

Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
