48 Wide Glass Shower Door - As it pertains to maintaining your home in tip-top shape, nothing can be more annoying than the usual sliding glass door that will not slide.
The number 1 reason your sliding glass door will not side is because too much soil and debris have clogged up the track of your door panel and the wheels. That is not a difficult fix, but because sliding glass doors are rather heavy, it is best if you've got another person present to help you.
You'll be able to closely analyze the track as well as the wheels, when the door is on its side. Most often, you'll find the wheels are full of soot and debris, and the path can be probably quite dirty. To clean the wheels, needle point and use compressed air pliers. Take care to pull every last hair out of the wheel bearings.
While you're at it, clean up all the "mating-borders" of the doorway. This is where the sliding door and some other surface of the door frame meet. A general rule of thumb would be to simply wipe down anything that seems filthy. Don't forget, even if the soil is just not necessarily on the trail itself, it may fall to the track causing your door to require another wipe down.
