Product review (5 stars): A cheap solution for refrigerator door gasket problems
We have an LG fridge that we really like, but like so many "French door" refrigerators, the door seals started sticking after 6-7 years. I inspected the seals and found that they were starting to tear, and the magnet/stiffener in the seal was starting to  warp at the corners, making things worse. I looked here on amazon for replacement seals and was disheartened to see that many people were having the same problem with the replacement seals.

So I decided to try something as a temporary fix and it seems to have worked amazingly well  so much so that we decided we didn't need new seals! What I did was to lubricate the seals with 100% silicone oil. I had some around for our Foosball table, and it seemed the right consistency for something like this. It's important to use 100% silicone oil on the seals because it will not damage the plastic seal... anything with hydrocarbons (HC) like WD40 or regular motor oil will eventually disintegrate the seal.

The result was immediate: the doors started opening and closing without sticking. That was a pleasant surprise. But what really shocked me was that the magnet/stiffener started to go back to its original shape! Apparently, the friction of the seals rubbing together was causing it to warp, and the reduced friction allowed it to flatten out again. So the doors just got smoother and smoother over a few months. Now they are essentially like new. They are still torn a little bit, but that doesn't seem to have gotten any worse.

So we saved money  and hassle with a little bit of lubricant. I told myself I would share this on amazon, so here I am. You can use any silicone lubricant you can find... we bought a bunch from a scientific wholesaler on eBay. Or you can just search for silicone oil here on amazon. We find that we have to renew the lubricant every other month or so, but it's easy by just wiping it on with a paper towel.

I hope this tip saves you some money and hassle. Even if your seals are too far gone and need replacing, I highly recommend you use a silicone lubricant regularly on the new seals. It seems to be a design problem with type of fridge.
