Michel F Round Rock , TX December 06, 2014 Appliance: Model WHIRLPOOL MW UPPER GRILLE Microwave upper vent grille broke Bought the replacement part. Pretty much plugs in without any problem. All I needed was a Philips screwdriver. Only minor issue is that the new part looks a bit whiter than the rest of the appliance which is 12 years old. Not exactly surprising... Just wished the part would cost a little less.... 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
