Catherine D Tacoma , WA May 24, 2015 Broken part The microwave vent cover at the top of the appliance in a rental was saturated with years of grease. Just touching it, grease dripped out. Removed it to clean and a plastic tab and screw hole channel broke, preventing it from being put back on. The replacement part was simple to install. 2 screws. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
