The Whirlpool 74001984 serves as an authentic replacement door hinge designed for Whirlpool wall ovens. It is a vital part that permits the oven door to swing open and close smoothly. The hinge is a metal bracket with a pivot point which attaches to both the oven frame and the door. When you open the door, the latch allows it to spin outwards, when you close it, the hinge guarantees that the door is correctly positioned to create a tight seal with the oven cavity. This tight seal is essential to effective cooking as it retains heat inside the oven and prevents it from departing. If your oven door isn't closing properly, looks bent, or swings shut uncomfortably you'll need to swap out the hinge.
