Magnetic Door Gasket

Magnetic Door Gasket. NSF Approved Parts and Materials. Flexible PVC and TPE gaskets with magnetic strip inserts provide energy-efficient seals without the use of door latches. These gaskets are NSF approved. Standard colors include light gray, black and white.

Freezers use magnetic sealing to make the cooling flawless. With a sealed enclosure, freezers trap air, and alternatively, it creates a positive system pressure inside.

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.

What is the magnetic seal
The magnetic seal takes care of the sealing between the door and freezer cabinet. It ensures that the cold air will stay inside so that the refrigeration compressor doesn't have to run continuously. 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.

How does the freezer door magnets work
The simple freezer door magnets is a sturdy option to line a freezer door. There's a magnetic core that mates with a flat plate on the swinging 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.

What's the reason for freezer door's pop-open
The complex air currents run across some units. With proper sealing, the chilled air temperature is controlled as well as a balance between the interior pressure and outer atmospheric pressure is maintained. If there is a spike of power output in the refrigeration unit, or there is another door opens suddenly, then it may cause a non-magnetised door open up all by itself. So, according to the law of physics, if the system will try to magnetise or balance the pressure, it may result in door pop-open.

Some door pop-open culprits
Did you know apart from the manufacturing errors, the chemical process due to the perishable items cause a difference to the freezer pressure? Moreover, the defrosting cycle raises the enclosure temperature.

With the rise of temperature, the molecules become excited and so the internal pressure. Whereas the equipment consistently delivers the balanced volume of air, the opening of outside entrance can cause the pressure equalization.

While capping of the content here, I must say that multi-door freezers use magnetic seal too. With the sudden change in pressure, the freezer door can be opened unless there is any magnetic field is fitted. To close the frosty chamber and keep items chilled, magnets should be in good condition to anchor the door. Call, any fridge repair service in Sydney if you find a problem with door sealing or magnet. And, keep these details in mind, as the unsecured door can cause a crack, which will consume more energy upon being used.

Has your refrigerator seal started to have issues, if so, you may be worried that your refrigerator seal has become demagnetized and you may be wanting a powerful magnet to re-magnetize it, but if you're still in doubt, don't do it?

If something is wrong with your refrigerator keep reading and maybe, you can fix it without needing to replace the entire seal. But firstly, we will run you through what not to do and explain where the magnet actually is.

Does My Refrigerator Seal Have a Magnet?
Running around the entire edge of every refrigerator door is a squishable gasket, that creates a seal between the door and the main body of the refrigerator. Embedded within this gasket is a flexible magnet, this magnet attracts to the steel body of the refrigerator ensuring a solid seal.

These flexible magnets are not as strong as neodymium magnets, but the long magnet does cover a large area. Even though the force is weak, the length makes up for this and it usually takes between 2.2kg and 4.5kg of force to open a refrigerator door.

These flexible magnets don't only have a weaker pull force, but the magnets also have a much lower coercivity, the measurement of a magnet's resistance to being demagnetized, making it easier to demagnetize these flexible magnets compared to a neodymium magnet.

How To Test If Your Refrigerators Magnet Is Still Magnetized
If you're unsure whether or not the magnet in your refrigerator is still magnetized you can test it using our Magnetic Field Viewing Paper, as this paper allows you to see any magnetic field produced by a magnet.

Clearly see the position of the magnet's poles and the pitching between them. Each sheet is super-thin and flexible and better yet can be used over and over again.

Things To Avoid Doing To Your Refrigerator Seal
Do not take a large neodymium magnet and rub one pole of it up and down the magnetic seal as this will completely demagnetize your refrigerator door and potentially nullify its worth.

With this in mind, grabbing a strong magnet when having issues with your refrigerator door should not be the first solution, instead, we have two non-magnetic suggestions that may fix your refrigerator door.
As most of the time, a faulty seal will not be caused by the magnet.

Two Non-Magnetic Fixes
Firstly, soap and water could potentially solve your problems. Simply proceed to clean the seal with a cloth soaked in warm and soapy water and rub the whole gasket to remove any built-up dirt and contamination. Also, be sure to clean the surface of the refrigerator's main body.

A gasket's flexible PVC metal ages it gets less flexible and more brittle over time, warming the gasket can help it match up to the shape of the refrigerator. Various sources online recommend using a hairdryer but avoiding getting too close to the gasket.

Gaskets that become worn, brittle or cracked, allowing warm air to circulate past the insulated doors. This causes the temperature to drop, warming the food inside thus creating a greater risk of food spoilage.

Cracked gaskets pose a health hazard by providing a hard-to-clean breeding ground for salmonella and other micro-organisms.

Poor-fitting or split gaskets also make the compressor work harder trying to keep the unit cold wearing out expensive equipment early and raising the cost of your electricity bill!

Gaskets form part of your regular Environmental Health inspections and if found to be faulty you may be granted a very limited time to replace them or face the appliance being condemned.
Hygiene star ratings are important to any food business. You could face losing valuable rating points by having faulty door seals.

We all need to do our bit for the environment so why send throw away a perfectly functioning fridge for the want of a new door seal. Simply replace and care for your door seals and the appliance could serve you for many years to come.

When should you replace your door seals?
When the door seal is not staying in the track and has become stretched and saggy.
When the door is not holding firm against the appliance. A good test is placing a £5 note between the appliance and the door. If you can pull out the fiver easily then the seal is not grabbing the door and allowing cold air to escape and warm air in. Just imagine that it's £5 notes leaking out of your fridge with the extra energy being used to keep it cool. Replace immediately with a new seal and save those fivers from escaping.

Check the seals when you clean them. Check for any splits between the folds of the gasket. The most common places are on the opening side of the door when people use the side to open the door instead of the handle and the top of the door seal where it's more susceptible to catching dripped liquids causing it to dry and harden. Don't forget to check the less obvious places like the hinges which can become pinched, if the hinges and door are not in line. Also, check at the bottom where the seals might come into contact with splashes from floor cleaning products. These are areas that your Environmental Health Officer will check.

If your fridge or freezer is icing up, which is a sign that warm air is getting in or if it's simply failing to maintain temperature – both point to a new seal being required.
