What are some common sliding barn door track problems?

A common sliding barn door problem is worn track wheels. These are the wheels at the base of the door, that grip a small piece of metal and are supposed to help close the door easily. Usually, they become worn down by traffic, and may have to be re-levelled and reinstalled. Another problem is a binding door spring or counterweight. Because they are so large, bar doors often require helper springs, to help take up the slack from the top cable. To combat this, regular cleaning and oiling should help. The same is true of the counterweight. There may also be problems with the track at the top of the barn door. These require cleaning and oiling, and the same is true of the wheels that turn in the track.
