Neff Oven Glass Door Shattered - As it pertains to keeping your home in tip-top shape, nothing can be more annoying than a sliding glass door that will not slide.
The number 1 reason why your sliding glass door will not side is because too much dirt and debris have clogged up the course of your door panel and the wheels. It is best if you have another person present to assist you, because sliding glass doors are very heavy, although that is not a hard fix.
You'll be able to closely examine the track as well as the wheels, after the door is on its side. Most commonly, you will find the wheels are filled with soot and debris, and the path is also probably very grimy. Needle tip and use compressed air pliers, to clean the wheels. Be careful to pull every last hair out from the wheel bearings. It's wise to be diligent in this measure, which means you do not have to make a habit of this process.
While you're at it, clean up all the "mating-edges" of the door. This really is where the sliding door and some other surface of the door frame meet. A general rule of thumb is always to simply wipe down anything that looks filthy. Don't forget, even if the dirt is not always on the track itself, it can eventually fall to the track causing your door to demand another wipe down.
