From simple fixes like changing batteries to more serious repairs like broken cables, there are many reasons why your garage door won’t open. Read on to learn some of the most common reasons your garage door won’t open, and when you should seek the help of a trained garage door technician.

Something is in the way

One of the most common issues with a malfunctioning garage door is a blocked photo-eye. Your garage door has a photo-eye on either side — typically six inches off the ground — that acts as a sensor. This safety feature prevents a garage door from opening or closing because it thinks something is in the way. 

If you don’t see an obvious obstruction, your photo-eye might be reacting to something small, like dirt, rocks, or a piece of debris. In this case, simply sweep the area, and check the photo-eye to ensure it’s clean.

There’s a problem with your remote

Another common reason your garage door won’t open might not involve your door at all. Before you assume it’s a mechanical issue, check the batteries in your remote transmitter. They may need to be changed out to get your garage door to open and close again. Also, make sure the signal from your antenna to the garage isn’t blocked by an obstruction (like tree branches), and that you’re within range for your remote to work correctly. 

Your operator isn’t getting power

If your transmitter is in working order and your garage door still won’t open, check that your operator is getting power. More often than not, it becomes unplugged by accident and needs to be plugged back into a power source. If your operator is plugged in and still not working, you may have a blown fuse, faulty outlet, or circuit breaker. For electrical issues, seek the help of a professional.

Your springs or cables are broken

Broken springs and cables on a garage door are fairly common, but they should also be considered dangerous and handled only by professionals. These are responsible for raising and lowering your garage door and, if they break, there is nothing to prevent your garage door from slamming shut with its full weight. This poses a serious risk to anything or anyone who might be in the way.

Another sign you have a broken spring or cable is if your operator is working, but your garage door won’t open. If this is the case, don’t try to open your door manually; call a garage repair expert immediately.

Your door is off-track

While cables and springs are responsible for lifting and lowering your garage door, the track keeps it in line. If you notice your door is slowing down or getting stuck while opening and closing, it’s likely it’s off-track. Check for any obstructions along the track, like any gaps or bends in the metal. You can also listen for squeaking noises to determine where the misalignment is. If the metal is bent or warped, it’s time to call a professional to get the track realigned or replaced.
