Answer Hello Arun. The damper can be checked by turning off the unit and then turn the unit back on. It should cycle open and closed. If the unit is cycling, it is good. If not cycling, test for voltage to the damper WR60X10063. If voltage is there, replace the damper. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
