This magnetic door plunger, also known as the magnet holder, is built for your washer. When you order this part, you will receive the plastic housing and a spring that goes with it. The magnetic door plunger attaches to the inner door panel of the washer. It holds the door open when the washer is not running, and allows the door and tub seal to dry. This prevents mold and mildew from building up. Occasionally, the plastic tabs on the housing can break, and when this happens the part will need to be replaced. You may also notice that your washer lid or door will not close; this can also be a sign of a damaged magnetic door plunger.
