James M Harwinton , CT July 02, 2017 The bracket to vent the microwave was missing and with a kitchen renovation I needed to purchase one so that the microwave could be vented. The repair is easy but the damper needs to be flexed to insert it into the holes in the bracket and it is extremely sharp so be careful not to get cut. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
