Fulmer, J Ellicott City , MD August 29, 2021 There was a tiny grease fire that damaged what I discovered was called the stirrer blade cover I was easy to fix. Take off the old piece, removed the pin and then turn a smidge. Keep the pin and the fan to use with the new cover. Clean the top inside of the microwave thoroughly while the cover is off then replace with the old fan and the old pin. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
