Charles W Vista , CA August 05, 2014 The cabinet contractor discarded the damper assembly when he installed my oven It took less than a minute to find the replacement part on your website and another minute to order it. The damper was delivered well packed and in good condition in a day and a half. It took about 15 minutes to install using only a small straight slot screwdriver to lift the tabs on the oven top. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
