John W Johns Island , SC November 22, 2015 Appliance: Model MT4155SPQ-2 The microwave door release bracket was broken Ordered the part from Appliance parts pros. The price for the part was reasonable and the repair was very easy. The only real issue is that you need a security torx bit to remove the housing from the microwave. Other than that a #2 phillips screwdriver is all you need to do this job. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
