Washer doors that will not stay slightly open or that close the wrong way can lead to moisture problems over time. A common cause is a worn magnetic door plunger. This small part helps control how the door rests when the washer is not running. When it fails, water can collect around the door seal and create odor or mold issues.
Replacing the magnetic door plunger is a simple repair that does not take much time. With a few basic tools and the correct replacement part, the washer door can return to normal operation and allow proper airflow after each wash.
What the Magnetic Door Plunger Does
The magnetic door plunger sits near the bottom of the washer door opening. Its purpose is to hold the door slightly open when the washer is not in use. This small opening allows air to move through the drum so leftover moisture can dry.
Air circulation helps keep the door gasket from staying wet for long periods. When moisture remains trapped, mold and mildew can grow on the seal and inside the drum. A working door plunger helps reduce that risk.
Over time, the plastic tabs on the sides of the plunger may crack or break. Once damaged, the plunger may fall out or fail to stay in place. When this happens, the door may not close correctly or may open wider than intended. In some cases, gaps around the door can allow water to leak during a wash cycle.
Common Signs the Door Plunger Needs Replacement
A failing magnetic door plunger often shows clear warning signs before it fully breaks.
- Washer door will not stay slightly open
- Door swings fully open on its own
- Door does not line up correctly when closing
- Visible cracks or damage on the plunger
- Plunger feels loose or falls out of position
- Water pooling near the bottom of the door
- Musty smells coming from the washer
Replacing the plunger when these signs appear can help prevent larger moisture-related issues.

How to Replace a Magnetic Door Plunger on an LG or Kenmore Front-Load Washer
Follow these steps to safely remove and install a magnetic door plunger so the washer door opens, closes, and stays in place correctly.
Preparation
- Unplug the washer from the power outlet and disconnect it from the water supply.
- Open the washer door to access the magnetic door plunger.
Tool Setup
- Straighten a paperclip, leaving one small elbow bend at the end.
- Flatten the paperclip with a hammer to create a thin, flat tool, or use a mini flathead screwdriver.
Removing the Old Door Plunger
- Press the door plunger inward slightly to create clearance.
- Place the flat tool on top of the plunger at the 12 o’clock position, aligned with the retaining tab.
- Apply downward pressure on the tool to press the tab inward.
- Pull the magnetic door plunger straight out of the washer door.
- Note that pressing either the top or bottom tab will release the plunger.
Installing the New Door Plunger
- Insert the new spring into the replacement plunger with the tapered end facing inward.
- Position the plunger into the washer door opening with the tabs aligned at the 12 o’clock and 6 o’clock positions.
- Press the plunger firmly until it snaps into place.
Final Check
- Open and close the washer door to confirm proper closing and magnetic hold.
- Reconnect the water supply, turn the valves on, and plug the washer back into the power outlet.
Summing Up
A magnetic door plunger might look like a tiny part, but it makes a big difference in how your washer stays fresh. When it holds the door slightly open, air can move through the drum, and the door seal can dry out after each load. That helps cut down on musty smells, mold, and moisture buildup around the gasket.
If your door swings wide open, will not sit slightly open, or the plunger feels loose, a quick replacement can fix the problem before it turns into leaks or odor that will not go away. With the right plunger, a few basic tools, and careful steps, your LG or Kenmore washer door can close the right way and still let the drum breathe between washes. After the repair, leave the door cracked open when the washer is not in use, wipe up any leftover water near the seal, and keep an eye out for early wear so the problem does not come back.
