After a few years of use, the seal on your refrigerator door might start to lose its magnetism. When this happens, it can cause problems with sealing and keeping the temperature inside your refrigerator where it needs to be. A weak seal can lead to poor energy efficiency, spoiled food, and your refrigerator not cooling like it should. The good news is you can remagnetize the door seal and make it last longer.

 

Understanding Refrigerator Door Seals and Magnetism

The magnetic seal on your refrigerator door is important because it keeps the cold air inside your refrigerator and the hot air outside. The seal on your refrigerator door is a rubber gasket with a magnetic strip inside it that runs along the edge of the door. The magnet in the strip lets the door stay closed tightly against the steel body of the refrigerator.

Most refrigerator door seals have flexible, ferromagnetic strips. In other words, the magnetic strip inside the gasket is flexible. It’s not a hard piece of metal. Over time, the magnet in the strip gets weaker because of normal use, changes in temperature, dirt, and the gasket getting out of alignment.

Common Causes of Magnetism Loss in Fridge Seals

Here are some common causes of why the magnetism in your refrigerator door seal goes away:

Wear and Tear: Every time you open and close your refrigerator door, the seal rubs against the doorframe. Over time, the rubbing wears out the magnet inside the seal, and it doesn’t work as well.

Temperature Changes: The seal on your refrigerator door goes from cold to warm and back to cold every time you open and close the door. This causes the magnet inside the seal to expand and contract, and it loses its magnetism over time.

Dirt and Grime: Dirt and grime can build up between the seal and the body of your refrigerator. This dirt and grime can keep the magnet in the seal from making good contact with the body of the refrigerator, and it won’t work as well.

Using Harsh Chemicals to Clean the Seal: If you use harsh chemicals to clean your refrigerator seal, you can damage the rubber gasket and the magnet inside the seal. This will make your seal not work as well.

Doors That Are Out of Alignment: If your refrigerator doors aren’t lined up properly, it can put extra pressure on the magnet inside the seal. This extra pressure will cause the magnet to wear out faster.

 

How to Remagnetize a Refrigerator Door Seal

If your refrigerator door doesn’t seal properly anymore, and you know the magnet strip is the problem, here’s how you can remagnetize your refrigerator door seal:

 

Step 1: Gather Your Tools

1)Strong neodymium magnets (get these at a hardware store or online)

2)Warm, soapy water and a soft cloth for cleaning

3)Scissors (if you need to replace the gasket)

 

Step 2: Clean the Seal

1)Turn off your refrigerator and let it come to room temperature.

2)Peel the door seal back gently and clean it with warm, soapy water to remove any dirt, grime, or other stuff stuck to it.

3)Check the gasket for any damage. If the seal is in bad shape, you may need to replace it.

 

Step 3: Test the Magnetism

Before you remagnetize the seal, you need to test to see if the seal’s problem is that the magnetism has gone away. Here’s how to do a simple paper test:

  • Put a piece of paper between the door of your refrigerator and the body of your refrigerator.Close the door.
  • Try to pull the paper out. If it comes out easily, your magnetic strip might need to be remagnetized.

 

Step 4: Remagnetize the Seal

Using strong neodymium magnets, here’s how to remagnetize the flexible strip:

  1. Hold two neodymium magnets together, aligning one magnet’s south pole with the other’s north pole.
  2. Slide the combined magnets along the entire length of the magnetic strip in a consistent, single direction. Repeat this process several times.
  3. Test the seal’s strength by using a small metal object. If the object is attracted to the strip, your remagnetization was successful.

 

Non-Magnetic Fixes for Fridge Door Seal Problems

While remagnetization can solve many problems, it’s important to consider non-magnetic causes for poor fridge sealing. Sometimes, the seal’s problems aren’t due to magnetism but rather dirt or misalignment. Here are two common non-magnetic fixes:

  • Clean the Seal and Fridge Body: Often, the simple act of cleaning the gasket and the refrigerator’s body can restore sealing efficiency. Use warm, soapy water to remove any debris or buildup that may be interfering with the magnetic contact.
  • Realign or Soften the Gasket: Over time, the flexible PVC material in the gasket can become brittle. If the gasket no longer forms a tight seal, warming it with a hairdryer (while avoiding direct heat) can help restore its flexibility and realign it to the refrigerator body.

 

How to Keep Your Fridge Door Seals Magnetic

To keep your refrigerator seal from losing its magnetism and keep it as efficient as possible, here are some maintenance tips:

  • Clean It: Gently clean the door seal with a soft cloth and mild soap. This will help prevent dirt from building up on the seal.
  • Don’t Use Harsh Cleaners: Don’t use harsh chemicals that could degrade the rubber gasket or magnetic strip.
  • Check for Wear: Periodically inspect the seal for any signs of wear or damage.
  • Check Door Alignment: Make sure the refrigerator door and body are aligned so that the seal doesn’t have any unnecessary stress on it.
  • Don’t Overload the Fridge: Overfilling the refrigerator can cause the door to misalign, which puts stress on the gasket.

 

Conclusion

Remagnetizing a refrigerator door seal is a simple, effective solution to restore your fridge’s energy efficiency and performance. By following these steps and properly maintaining your seal, you can extend the life of your fridge and keep it running at its best. If the seal is too damaged or the magnetic strip too worn, consider replacing the gasket for optimal results.
