Lori D Circle Pines , MN September 25, 2016 Appliance: Whirlpool Microwave Hood Combo MH8150XJT1 Whirlpool Microwave Mh8150xjt1: Broken door handle. How to replace Door Handle (Bsq). After a few weeks of contemplating and unscrewing and screwing in door screws which were completely unrelated to the actual fix, I searched youtube for a video and mastered the task in 10 minutes by popping the back panel off the door, unscrewing the broken handle and replacing it with the new one. Thank you youtube and thank you Appliance Parts Pros for shipping me the handle within 3 business days at the lowest price available !!
