How to magnetize new refrigerator door gasket???? Answered

Refrigerator door gasket came unmagnetized. Very expensive, and, royal frustration thus far.
Got the thing installed okay, but there is no 'seal'. Supposedly, according to Whirlpool, they don't need magnets in the fridge door gaskets to seal.....(Yeah, right)
Any way to make a gouzer?
Figured I could depend on help here. If I had enough magnets, I'd make my own.
Also, why are the gaskets on the door?

I'm just looking in to this problem. The magnets inside the seal (grommet) are made from rubber laced with particles of ferromagnetic material. The manufacturers use large magnets to align domains within the metal. These area are sometimes North-South side by side or alternating small slices across the bar. This helps give extra attractive power to the strip by making it act like a horseshoe magnet.
But here's the rub; Coercivity - how hard it is to push a magnetic domain to align - even these rubbers need a very dense field.
I am going to try side by side by rubbing neodym magnets in a horseshoe configuration along the length, keeping, say, South inside and North outside.
I'll report later.
Incidentally replacements cost £100 here so there is a high probability prices are a marketing man's fantasy.

Old magnets work but have a few broken spots towards the bottom. New magnets arrived and barely stuck. The old ones were better formed. Other than that advantage it would be nice to test the magnetic field between the two of them.

If it didn't come magnetized then there probably is nothing in there to magnetize.

Seconded - the fridge probably has a vacuum pump that keeps a negative pressure inside and sucks the door closed.

Really ? Never seen one of them on this side.

Yeah, my last one (quite new) in a condo I rented you closed the door, and it had an obvious magnetic seal, but then you heard a hissing sound that got higher and higher pitched until it suddenly stopped - at which point you were certain the seal was 100%

When you think about it - air pressure works on area - so 1psi difference at 1296 square inches is a LOT.  probably only a tiny fraction of a pound of pressure, or you'd never be able to open the door.

Physics: You open the door, you let warmer air in. You close the door, the air is cooled, and contracts. Thus the negative pressure and the sucking sound. That's why it's so hard to open the door immediately after you've closed it, but easier later. There's no pump. Just physics.

Presumably there's a pressure sensor then - do you hear the pump fire up periodically ?

Totally silent - all you hear is the hiss of air for a few seconds when you close the door.

My ref. an upright freezer are both that way.  I like them better because the magnets loose the pull eventually if you keep them long enough.

Cool idea. How long do they need to pump down for when you close the door ?

It's instant.  Doesn't take much of a vacuum but they seal really well.

How do you get back in ? Can you just pull the door open ?

Yep.  Like I said it's not much of a vacuum and it takes just a little tug to break it.  Although, small kids seem to have a hard time opening them.

Although, small kids seem to have a hard time opening them.

What would worry me is that someone is stoopid enough to get stuck inside, in the way kids died in the old days, before mag-seals.

No, it's not that kind of hard at all.  No chance to get trapped.  THey seem to just want to give a small jerk and what it takes is a small tug to break the seal.  If anyone were on the inside just leaning against the door would cause it to come open.  It does'nt lock at ALL..

I just rubbed a strong 2" magnet along my freezer door gasket a few times. I found that the hinge side of the gasket was repelling and not attracting, so I flipped the magnet around a couple of times and kept rubbing it along that section and low and behold, it became magnetized. All 4 sides of the gasket are now much stronger magnetically and there is a noticeable positive pull on the door which it did not have before. So easy.

Hi! Once you get that gasket magnetized, don't forget to wash it with a little bleach and water. That will prevent mold and mildew from damaging the gasket. This article has some more tips on
refrigerator gasket care.

Magnetize the gasket again.

Gouzer?
The gasket is to seal the fridge and keep cold air in. If it's not magnetic, I guess it's held by pressure and the door has a lock?

Did the original have a magnet, I'm guessing so? In which case, given that it doesn't work for you, they have supplied you with the wrong part. Reject it as the wrong part / unfit for purpose and ask for your money back or a replacement.

If the gasket isn't sealing, you might have to adjust the hinges to get the surfaces to match-or the door is warped : (
