The KHMS155LSS is a legacy KitchenAid over-the-range microwave now approaching two decades in service in surviving units. Owner reports on this model document two specific recurring issues: a door handle prone to cracking with age, and a vent grille that can work loose or detach — both mechanical wear points distinct from the microwave’s cooking electronics, and both worth addressing before they progress into a bigger repair.
