Amy R Mokena , IL October 17, 2014 Broken plastic microwave vent grille We bought a house and the microwave vent grille was filthy. While I was cleaning it, it just broke right off, the plastic snapping at the points where it screws in. Fortunately, Appliance Parts Pros had a perfect match, they shipped it quickly, and now we're back in business with a clean, new unbroken vent grille. 18 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
