The Whirlpool 8169464 is a white replacement outer door frame that fits your Whirlpool microwave. This is the outside plastic piece which covers the microwave door's glass window and the inside panel. It attaches to the present door framework, keeping everything together. If your original door frame has been broken, scratched, or discoloured, replacing it with the 8169464 may enhance the look and function of your microwave door. The damage has no immediate impact regarding the microwaving process, but a cracked outside door frame may compromise the seal between the door and the microwave cavity. This may end in microwaves seeping out, which is ineffective as well as hazardous.
