Why Won’t a Garage Door Go Down?

One of the biggest problems with garage doors is a malfunctioning closing mechanism.

One of the biggest problems with garage doors is a malfunctioning closing mechanism. It’s a significant inconvenience because it increases the risk of injury while inviting burglars, rodents, and other threats into the area.

The first step to solving the issue is to understand the potential causes:

Dirty photo-eye sensor

Photo-eye sensors are devices mounted on the sides of the door, sending signals when the unit is closing. However, the door may fail to lower if something interrupts the signal to prevent an accident. The most common culprit is dust or dirt accumulation on the sensors.

Obstacles under the garage door

Dirt, rocks, grime, and many other objects can block the path of a garage door. In that case, the unit can’t close fully and keeps reopening.

Misaligned sensors

Photo-eye sensors must face each other when sending signals. The lights should run steadily if a garage door contractor has aligned them correctly. By contrast, misaligned sensors often lead to blinking LED lights, keeping the door from lowering.

Misaligned track

A garage door can only open and close correctly if the track is aligned. This metal component is essential, as it supports the unit in motion.

Problems, such as gaps between the track and rollers, can cause misalignment. The track might also be bent.

Disconnect switch

Modern garage doors come with disconnect switches. Once active, they enable the owner to manually open and shut the door. It’s a handy configuration in power outages and presents an alternate way of using the door when the remote is broken.

Still, it can also be inconvenient when activated accidentally since it keeps the owner from closing the door with the remote.

Broken springs

Depending on the cause, a garage door doesn’t always stop similarly. It either halts suddenly or gradually. The former can happen if the garage door has broken springs.

These parts of the mechanism do all the heavy lifting, ensuring the door goes up and down smoothly and safely. A broken spring is a serious problem that can keep the unit from closing. It should be addressed promptly by an experienced garage door professional.

Dead batteries

People can’t close their garage doors if the units don’t have power. The transmitter provides energy, but only if the batteries are full. Otherwise, the device doesn’t signal to the rest of the mechanism, so the door stays in place.

Find the right solution

Fixing a garage door that won’t close depends on the cause. The best way to identify the culprit is to hire a licensed garage door contractor. They’ll use cutting-edge equipment and advanced skills to repair the unit.
