Sharol M Mondovi , WI July 13, 2015 Appliance: Model MH1160X5Q-2 The grill vent was broken by people reaching into the cupboard above the microwave The plastic tabs broke away from the screws holding the grill vent to the microwave so even though I was able to put the grill back in place, it didn't stay. So I ordered the new part, and my husband replaced it easily with a screwdriver. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
