Closet Doors With Frosted Glass Panels - In regards to maintaining your house in tip top condition, nothing can be more annoying than the usual sliding glass door that won't slide.
The number 1 reason your sliding glass door won't side is because too much soil and debris have clogged the wheels and the track of your door panel up. This is not a hard fix, but it is best if you have another person present to help you because sliding glass doors are very heavy.
When the door is on its side, you can closely examine the wheels along with the track. Mostly, you will find the wheels are full of soot and debris, and the course is also probably quite filthy. Use compressed air and needle tip pliers to clean the wheels. Be careful to pull every last hair out from the wheel bearings.
While you are at it, clean up all the "mating-edges" of the door. This is where the sliding door meets with every other surface of the door frame. A rule of thumb of thumb will be to simply wipe down anything that seems filthy. Don't forget, even whenever soil is not always on the path itself, it may eventually fall to the course causing your door to need another wipe down.
