What Causes Garage Door Not To Close?

Causes of Garage Door Not To Close

Many homeowners find their garage door is all of a sudden not closing completely or just staying half-open. A garage door may also be out of sync with the rest of the home. Today, we will share about why your garage door may not be closing, randomly or every time.

Many people experience their garage door not working correctly. Usually, before garage doors go totally dysfunctional, there are visible signals that we can see and act immediately to avoid bigger damage. If your garage door is not closing, then it can occur due to some of the reasons mentioned below.

1. Security sensor

Sometimes faulty security sensors can restrict the garage door from closing. Sensors, safety lasers, or photo-eye are mounted near the floor by the tracks. These sensors assist the door in detecting children, dogs, and obstacles in the way of garage doors, ensuring that no one is injured. When these sensors are dirty, misaligned, broken, etc; they send false signals to the garage door openers and the door remains half or completely open.

2. Remote batteries are dead

Remote batteries can also be the reason for the issues related to doors not closing. Garage doors require power from both sides, including operators and remote, to work perfectly. If your remote transmitter does not work, then it means that your remote batteries are dead.

3. Operators receive no power

As previous point, the garage doors need power from both ends. If you think that your remote is working perfectly then it can be a problem with your operator. This problem occurs due to the no power supply in the operator. Sometimes, people accidentally unplug the operator’s cord, resulting in no power supply. There can be more reasons but the power supply is the most common one.

4. Faulty tracks and rollers

Faulty tracks and rollers can also stop your garage doors from closing or coming downward. An obstacle in the tracks can be a reason for this problem. Additionally, bent tracks can also be a reason to stop your doors from closing. Sometimes, rollers also need lubrication to work smoothly. If the roller is not lubricated, it may be damaged and become an obstacle in closing and opening a garage door.

5. Broken coil spring

The garage doors rely heavily on various springs. The major spring is the torsion spring. If the torsion spring or any of the other springs gets broken or damaged, then it could stop garage doors from opening and closing. Fortunately, it is easy to diagnose this problem. An inspection by the homeowner can diagnose this problem. You would see the coil spring in two parts on the top of the garage.

The life of spring is rated for a specific number of cycles. One-time garage door opening and one-time closing are counted as one complete cycle. Spring that is used beyond its rated life cycles is highly risky and can cause serious damage. Sometimes, spring can break before reaching the rated life cycle. No matter how springs get broken but a broken coil spring is a dangerous situation. We do not suggest undertaking a DIY project for a garage door’s broken coil spring.

6. Defective trolley

The trolley is a mechanism that connects the garage door to the opener or operator. This trolley can be easily identified as a rope hanging from it. This rope engages and disengages the door from the chain-driven from the opener. If the trolley is on bypass mode. Then it can be a barrier to the movement of the garage doors.

7. Misadjustment sensitivity

Misadjustment-sensitive settings can also stop your garage doors from coming down or closing. Sensitivity sensors help openers know how much force is needed to raise or lower the door. If the sensitivity setting turns off, the opener will face difficulty in identifying the weight of the door and the force required to operate the door. Consequently, the opener will not react to the activation prompt, and the garage door will not open.

8. The remote signal is blocked.

Indeed, if the remote battery dies, it can be a reason to operate a garage door. But if remote batteries are perfectly working, there could be an obstacle between the remote and the opener. Additionally, you might be out of range to operate the door from the remote. Sometimes damaged remote antenna can also be the reason for this problem.
