You might have noticed that you try closing your garage door and immediately before it hits the floor, the garage door reverses and opens up again. This is a common garage door problem that most people face which can be caused by a number of different factors. It can be really annoying because it leaves your house prone to security risks as the door refuses to stay closed. One of the common causes of this problem is problems with the rollers.
The garage door needs regular service so that all the parts and mechanisms are checked and any problems taken care of. Neglecting the door for instance may cause problems with the rollers like rusting which can cause the door to reverse before it hits the ground. To avoid rusting and to ensure free movement of the rollers, ensure they are well lubricated and taken care of. Also, check to ensure that the rollers are not damaged in any way or there isn’t any debris build up on them that can make movement of the door problematic.
If the rollers are in perfect condition and the door still behaves this way, it is probably because the close force setting needs adjustment. The garage door has an adjustment screw that sets the closing force of the door. This screw is on the garage door opener. When the force has been set too high, there is high friction on the rollers which causes the opener to think that the door has reached the ground thereby terminating motion. When motion is terminated mid way the door reverses immediately. When this is the problem, the door opener should be adjusted so that it has less sensitivity. This means the door will close with ease and reach the bottom without stopping mid way.
The garage door should be serviced and maintained regularly to ensure that such common problems are kept at bay. All the parts should be checked for problems and repaired immediately. This saves you major damages to your garage door which can cost you major bucks during garage door repair exercises.
