Do-It-Yourself Stories from Customers like You Microwave blew line fuse   Gerald G. • St. Louis , MO • August 05, 2019

Do-It-Yourself Stories from Customers like You Re routing microwave exhaust   Karissa B. • Brookhaven , GA • October 19, 2015

We bought a house with an over-the-range microwave, which just recirculated air into our house--not effective for smoky meals! We removed the microwave and cut a hole to send the exhaust out the back of the microwave (and out of our house), but realized we were missing this damper and frame that go on the back of the microwave for rear exhaust. The parts fit perfectly and now we can enjoy a smoke-free kitchen! Read more
