James for Model Number CVS36RB downdraft Push the snokel up/down button to activate the unit. Vent comes up and down continously. Wont stop unless you unplug it or push the up/down button. I replaced the up/down button 2 years ago because it would no longer activate the unit at all. It solved that problem at the time.
Answer Hello James. You need to check the directional switch in the unit. If it is bad, it will cause the issue you are having. You can test this with a multi-meter TJMA-DMT3. 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...
