7 Reasons for your Garage Door Not Closing All the Way

Is Your Garage Door Not Closing? These 7 Reasons Are to Blame…

One or more of these reasons is likely responsible for your garage door closing partially, but not all the way:

1. Something blocking the door

Though this problem should be obvious, it shouldn’t be overlooked. If there’s something blocking the door from closing all the way, a full close will be impossible. Check your garage floor and the area surrounding it for any objects or debris that might be causing the improper close. You may also want to check the tracks, and the garage door itself, for the culprit.

2. Faulty safety sensors

First, and perhaps most commonly, your safety sensors could be working improperly. These twin sensors usually sit near the bottom of your garage door, less than 6 inches above the ground. They face each other, sending a signal across the length of the doorway to determine whether there is anything in the way of the closing garage door. If one or both of these sensors are not receiving power, or are not emitting the signal properly, your garage door will respond by failing to close all the way. This is a safety feature, but it can be annoying when there isn’t anything actually blocking the door. If the root cause is a sensor failure, you can purchase a new pair of sensors and replace the faulty ones.

3. Safety sensor misalignment

In many cases, the photo eyes are working properly, however, they are sending a perpetual signal to your garage door that something is in the way as a result of misalignment. This can occur if one sensor is struck or moved out of place. Conveniently, most sensors are equipped with a light that informs you whether they’re in alignment or not; when the light is on and solid, both sensors are aligned and functioning properly. When the light is blinking, they’re out of alignment. This problem can usually be corrected by returning the sensors to their proper orientation.

4. Broken springs

Garage doors rely heavily on various springs to open and close with ease. If any of these springs are broken or damaged, it could lead to the door becoming misaligned and not closing properly. Fortunately, it’s easy to tell when one of these springs has been damaged; a brief visual inspection, even from a non-expert, will be able to diagnose the problem almost immediately. We recommend leaving all spring repairs to a professional.

5. Damaged cables

All garage doors depend on some sort of cabling to lower the door properly. If any of these cables are worn or damaged, they may not be able to complete the task properly. In most cases, a thorough visual inspection should be able to spot any damaged cable. We recommend leaving all cable repairs to a professional.

6. Door travel limits

You may also have a problem with the travel distance setting on your door. In most garage door openers, there’s a default setting to tell the garage door how far to close. This can be improperly set upon installation, or slowly drift away from the original setting over time. If the setting is too high, the garage door will stop short of the actual ground. If the setting is too low, the garage door will “think” it’s hit an object when it’s actually hit the floor. Either way, you’ll need to adjust the door travel limit setting. Different models of opener have different means of achieving this, but it’s usually done with knobs on the machine itself.

7. Damage to the tracks

Finally, if the tracks responsible for carrying the garage door down have been bent, warped, or otherwise damaged, it may prevent the door from closing properly. If the tracks are blocked, a simple removal of the blockage should be enough to restore working order. Otherwise, you may need a track replacement.

Fixing Problems on your Own

As you’ve read, some of these problems can be easily fixed on your own. For example, if there’s something blocking the door, you can move the object and hopefully, the door will return to its normal movement.

However, there are some issues that are better left to the professionals—especially if it involves parts of your garage door that you don’t fully understand. Overhead torsion springs, for example, are tightly wound and carry high loads of tension. If improperly handled, they can cause severe lacerations or damage to your house. Plus, if you attempt to fix something on your own without fully understanding your actions, you may end up damaging the garage door even further.
