There are a number of myths that need busted on these and some advice that will probably help you with a faulty door seal
You'd Think It Was Simple!
Like most spare parts or components things are not as simple as people often presume that they are, usually thinking that they're all pretty much the same when in fact, nothing could be further from the truth.
You've got hundreds and, we do mean hundreds of different gasket profiles then after that probably thousands of different sizes. Then atop that, you've got ones that are foamed or bonded into place, ones that aren't and so on. The net results is that there are tens of thousands of possibilities.
Standardised seals or gaskets, no, they do not exist.
In short, if you want to replace the door seal on your fridge or freezer, don't guess as that often ends badly.
We're not being snarky, difficult or anything, we're merely pointing this out to try to save people from making either an expensive mistake or giving themselves a heap more grief that they need to.
But do take the time to read the specific article about fridge and freezer door seals here that explains a bit more about finding the correct one.
Split Door Seal
A split door seal is a common thing to see and likely the most common reason to replace one.
Often times it's as the seal is pulled rather than the handle and eventually the seal just gives it up and breaks, splitting open.
With some, you can patch them up with the likes of Sugru (Google is your friend to find that) but if the split is severe then this may not be possible and all you can do is replace the seal.
Perished Door Seal
There's nothing you can do but replace it if you can, there's no saving them from the ravages of time, sorry.
If the seals starts to age prematurely and look perished at a relatively young age then the chances are there's something in the environment that's affecting it.
That can be heat, moisture and so forth but there will be a reason and, it will not be the seal as such that's the problem.
Warped Door Seal
Another that we see a fair bit is warped seals or they get compressed over time and, just like when they are being fitted all too often a hairdryer is your friend here.
Get some gentle heat (don't use a paint stripping heat gun or anything as harsh) into the seal and it will become more pliable for fitting and often as not "pop" back to it's original shape.
This is something filed service guys do all the time when fitting new seals and getting them to refresh themselves as well. It's worth trying this before you do anything else on an old seal you think it a bit out of shape as after all, what's to be lost from trying?
This is a myth.
Door seals won't de-magnetise or lose their magnetism over time. Well, they might do but no need to worry as it'd take so long as we'll probably all be dead so, not really a concern.
Normally we hear this when people think that's what the problem is, they want a new seal to solve it, usually on integrated units only to go do that then find out the actual problem was the door hinges.
So, in order to save many people a lot of hassle, time and money we thought this worth a mention.
Changing a Door Seal
In the bad old days...
You had a bunch of screws under the lip of the seal, you undid them, the inner door came off and you could easily change the seal.
People wanted more space, efficiency gains required both by buyers and governments and lower pricing so, lower cost production led to what we call "foamed doors" or "bonded doors".
What happens is that they put the outer door, inner door and the seal all sandwiched together then inject insulating foam into the door essentially glueing it all together as one unit. The whole lot is bonded together as one unit.
On these, well a lot of them, it's not possible to change the seal at all and on all of them, it's a pain.
Where you can, there are two ways to do it depending on how the manufacturer does things.
Stick A New Seal On
You get a kit and you cut the old seal off with a very sharp blade, mind your fingers and use a very new, very sharp blade so it's neat.
Then you take the sticky kit and put the double sided sticky stuff where the new seal goes.
Put the new seal on.
Leave it for a few hours to bond.
Put the door back on.
And, that's the easy ones to do! It's actually not that hard, just fiddly and time-consuming really.
The Other Way!
This way is hateful.
You need to gently prise up the inner liner after sometimes trying to get a blade or something into the back if it to loosen it a little.
Then you need to gently work off the old seal with the liner in place all the while.
Then you need to work the new seal on.
Then hope it holds okay!
This is horrid to do, most field guys hate doing these as they are a royal pain to do and get neat so people often ain't that happy with the end results and they're not exactly sound.
You can get some silicone on it to try to hold it a bit better but that's hit and miss as well.
Universal Fridge & Freezer Door Seals
Yes, they do exist and yes, we do sell them.
They are not an easy option however and they take time to fit. Where you stray outside the norm, such as it is, then you get into all manners of profiles, ordering to size, jointing kits and a bunch of other stuff.
If you need, just ask us for help on these or any other seals.
Not So Easy
The points we're making here are that it's often hard if even possible to find the correct door seal and even when you do, it can be expensive and not easy to replace it, just because of how modern domestic fridges are made.
They're made that way because of primarily market but to a degree (it can be argued) for environmental reasons but, most market-driven.
