Mark P Algodones , NM August 24, 2015 Appliance: KitchenAid Microwave Hood Combo KHMS155LSS4 Kitchenaid Microwave Khms155lss4: Door handle on microwave broke. How to replace Microwave Door Handle. Total time to remove and replace handle took approx. 45 minutes. Initial seal (plastic) on inside of door took the most time separating from glass and frame. Once that seal is removed, one must pry up internal lock tabs restraining main glass frame on door. Again, a very slow process to ensure plastic and metal is not broke or distorted.
