When Garage Doors Won't Close

The main rule is that garage door maintenance will keep the system in perfect condition but you cannot exclude completely the possibility of some problems, especially if your house is affected highly by fierce natural phenomena or you had a small car accident lately. After all, the most consistent homeowner would maintain the system once or twice a year but in the meanwhile things change, garage door parts get a few months older and the smaller problem could keep the door panel from not closing properly. Imagine that a rusty hinge or brackets missing a few screws will be too weak to hold the weight and tension of other components and could cause malfunctions. So, it's good to check them often or know where to look when you find your door a few inches higher from the floor.

Check why the garage door won't close all the way

It is essential to check the tracks because a door not closing or even opening all the way is possibly a sign of damaged garage door tracks. In this case, the rollers would find it hard to continue their trip along the tracks and the door would either come off tracks or won't reach the floor. You will have similar problems with loose cables, especially when the hinges are not tightened causing the cables to dysfunction. When the extension springs for garage doors are damaged or at least one of them has lost its flexibility, the door won't open or close evenly. As a consequence, the door won't find the floor at both sides and remain half open. When you are looking for the causes of such problems, it is natural to check the obvious suspects first. The door is expected to remain open if there is an obstacle underneath because this is the job of the garage door opener safety sensors. So, check for an obstacle in the form of a small rock or tree leaves and examine the condition of the sensors as well. In case the infrared sensors won't work properly, you won't only have security problems but also basic safety issues as well.
