Most refrigerator seal flexible magnets are magnetized with the face showing two areas of different magnetization direction, degrees opposite from one another. This ingenious setup enables this weak magnet to get a much stronger hold on the nearby steel surface. It also shapes the magnetic circuit in a way that helps reduce the chances of demagnetization, like a keeper on an old horseshoe magnet.
A piece of green MV43 magnetic viewing film helps illustrate the magnetization. This film shows a light colored line anywhere the field direction is parallel to the film in the plane of the film. Placing this sheet on top of your fridge gasket should reveal either the single or double line pattern.
Strong neodymium magnets can re-magnetize these flexible magnets. We experimented and tested a number of ways to re-magnetize these flexible fridge magnets. Our goal was to prove out a few suggestions about how to re-magnetize them by just rubbing some combination of neodymium magnets against them, without having to remove the seal. We started with a small strip of this magnet material we scavenged from an old refrigerator door. Can we match it by magnetizing it ourselves? By sliding the flexible magnet into the gap between two large, attracting, BX0X08 magnet blocks, we re-magnetized the flexible magnet to have a single magnetization direction.
This setup exceeds gauss in the gap! After passing through this gap, pull force testing of the flexible magnet measured 0. Changing the magnetization scheme to present a single pole to the face of the fridge just doesn't work as well.
We repeated the process with the same magnetization setup, but this time through the wider width. The result is a single magnetization direction through the wider direction. Pull force testing of the flexible magnet was better, but still only 0. Placing two of these magnets side by side, the top surface has its north and south poles showing.
By rubbing this against the flexible refrigerator seal magnet, centered on the fridge magnet, we can magnetize it more like the original scheme. After rubbing this against the magnets a few times, we measured 0. We initially assumed this scheme would fully re-magnetize the flexible magnet.
We were surprised to see this result fall a little short. If your fridge seal is completely demagnetized, rubbing a pair of BX block magnets arranged this way along the problem area might offer some real improvement.
It might not get to the full, original strength, but it could improve matters. If you find that the seal does have some magnetization, try orienting these magnets to reinforce it, magnetizing the flexible magnet in the same direction. In our last-ditch effort to re-magnetize the flexible magnet, we set pairs of BX magnets on either side of it. Subsequent pull force testing still only yielded 0.
It might need cleaning, or a bit of heat to reshape old, less flexible PVC material. What if I filled the gap between the door and the body of the fridge with a stack of magnets placed outside of the gasket area? If those magnets attract to hold the door shut tightly, would that be enough to squish the gasket? Maybe, but it would not address a deformed or raised area somewhere on the gasket. We found a few fridge seals that used 3-pole magnetization of the flexible magnet, rather than two.
If all else fails, you might try this with three BX magnets side by side by side. So, if you open or close a freezer with less care, the positive pressure causes the pop-open effect to the door.
So, if there is a magnet, it prevents the seal-breaking incidents from occurring. The magnetic seal takes care of the sealing between the door and freezer cabinet. Even, the refrigeration unit will get an extended life span while saving the energy.
The magnetic seal of fridge gasket is found between the sealing doors and drawers of the refrigerator and freezer. The magnetic fridge seal is designed to hold the magnetic strip that ensures that the fridge door stays closed within an airtight seal. You may opt for fridge repair in northern beaches if you find your door sealing is loosing the grip like before. The simple freezer door magnets is a sturdy option to line a freezer door.
It creates the discrete fittings that are replaced by an extruded gasket to offer a flexible seal with magnetic properties. The magnetic gasket holds the swinging panel securely, even when the positive pressure rises.
Though fridge repairs in Bella Vista is an inevitable part to fix this issue, you can clean it too with a few steps. Dip an old toothbrush into the mixture of dish wash liquid scrub the dirt out from gasket. However, proper cleaning is required to stop the area from attracting dirt and germ on a frequent basis.

Find the discourse below from our experts to be aware of such issues — You might have checked that there is nothing inside to push the refrigerator door, but there is still a problem in proper closer. Find it in detail — 1. Too Much Weight in the Door: Upon storing the heavy items like gallons, juice or milk with a heavy container can create an excess weight. Check the Seal: The seal around the refrigerator or freezer door is also called a gasket.
Clean the Gasket: At times, the fridge door will pop open on its own.
