Donald S Oakdale , MN February 28, 2015 Grill vent on microwave oven supports broke I ordered item and learned that is was on back-order. It finally arrived a couple of months later. Installation was very easy. It has tabs on the bottom that fit into holes. Two tabs and screws secure the vent to the microwave. Installation took less then 5 minutes. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
