Back in our article about halbach arrays we showed how flexible magnets are magnetized in multiple directions they re not magnetized in one direction throughout like a simple neodymium disc magnet.
Remagnetize fridge door seal.
It seals in the cold air so foods stay fresh.
The seal around your refrigerator or freezer door also called a gasket does exactly what the name implies.
Magnetic strips embedded in the door s gaskets are responsible for making the door shut tight so run that magnet 50 times along each side of the gaskets all in the same direction.
Before we show how to remagnetize a flexible magnet let s take a look at how they should be magnetized in the first place.
For example if the gasket is held in place by screws use a screwdriver to remove the screws.
Even if it stays shut for now eventually little cracks develop in the gasket letting cold air out.
While a new flexible door seal almost always sticks once the gasket gets old and brittle it may have issues.
If your refrigerator still isn t closing tightly check to see what you re storing in the door.
Close your refrigerator door on a dollar bill.
If adhesive strips are in place use a putty knife to pry the gasket away from the refrigerator door panel.
If the freezer door seal is torn try using a gasket repair kit to fix the gasket so the door will seal.
It seals in the cold air so foods.
We used r821 ring magnets for the job and t.
If the bill slips you ve got a loose seal.
If the door seal is demagnetized try rubbing a strong magnet along the freezer door gasket a few times to re magnetize.
Use the appropriate tools or methods to remove the defective gasket.
Clean the complete door gasket with hot soapy water and the frame where the door gasket makes contact.
To get that seal snug again find a strong magnet.
K j magnetics demonstrates how you can remagnetize a flexible fridge magnet using an array of neodymium magnets.
The magnetic sealer on the freezer side is very strong and pulls the door closed tight but the one on the refrigerator side is week and when i close the freezer the refrigerator side pops open.
I have a side by side and the refrigerator side does not close as tight as the freezer 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.
