There’s a lot that you can do before you know that you need to call in a refrigerator tech.
The Vaseline treatment
Replacement refrigerator gaskets aren’t expensive, but the replacement process can require painstaking work. If you’re planning on changing out the gasket yourself, you need to know that it can be hard to find the exact replacement part for your model, as well. It’s a much better idea to call a tech in. There’s a simple fix that can bring an old gasket back from the dead, though.
Plastic and rubber tend to dry over time. It is this drying action that hardens and deforms them. Luckily, it’s possible to reverse the drying somewhat, and make rubber supple enough for further service. Surprisingly, some Vaseline usually does the trick.
All you need to do is to get a little jar of petroleum jelly, and rub it all over the gasket, especially the part that makes contact with the refrigerator cabinet. A few days later, the stuff should soak in sufficiently to soften the material, making your gasket serviceable again.
Vaseline can also work well as a preventative, ensuring suppleness for years.
You should look into a couple of other possibilities
Sometimes, when a door won’t close as well as before, it has nothing to do with the gasket. Rather, it is poor level setting that is to blame. Simply turning the level setting screws at the front end of the refrigerator to have the front tilt upwards a little bit, can result in improvement in door contact power.
If you like to put heavy bottles and other stuff in your door racks, they could be a reason your door has trouble, too. You should try unloading the door. A lightweight door can be a good way to help with door grip. If it doesn’t help, you could try tightening the hinges.
Not every kind of door issue can be fixed with a couple of simple maintenance moves, unfortunately. There’s a lot of you can do with them, though, and it’s always sensible to try them before calling in the professionals.
