Batteries are Dead
The first step should always be checking the batteries in your transmitters. This is the most common problem and the easiest one to fix.
Without batteries, your garage door can't get the signal that it needs to open or close.
Check the transmitter inside of your garage first. If it opens and closes your door, you need to check the remote transmitter. There is a tool you can buy to check the charge in alkaline batteries. Without that tool, you can check for dead batteries with a little trick.
Drop the batteries in question from a few inches above the ground. If the batteries make a loud thud and stay standing, they're not dead. If they don't make a sound and fall over, the batteries are dead.
Once you find dead batteries in your transmitter, all you have to do is change them. With new batteries, test to make sure your garage door opens.
Try to take note when you change the batteries so you can get an idea of how often you'll have to change them.
Dead batteries aren't the only problem you'll have with your garage door transmitters. As convenient as they are, they come with some hiccups you'll need garage door opener troubleshooting knowledge for. If your garage door won't open when you use your remote, you might be out of range. Wait until you get closer to your garage before trying to open it with your remote.
If you know you're in range but it still doesn't open, check the transmitter antenna. The antenna should be hanging from the door's motor. If the antenna is obstructed, your transmitter can't tell your garage door to open. If the antenna is damaged, you may need a repair for your transmitter to work again.
Is your garage door opening and closing seemingly on its own? This could also be an issue with your remote.
Make sure your remote transmitter isn't stuck under a seat or other object in your car. Sometimes the button can get stuck and run your garage door ragged.
If your remote isn't being pressed, your neighbors could be opening your garage door with their remote. If your neighbor is running their transmitter on the same frequency, change frequencies to keep them from controlling your garage door.
Faulty Photo Eye
Your garage door has a photo eye on both sides that prevents it from shutting when something or someone is under it. While this safety feature is super convenient, it also makes room for complications. If the photo eyes are dirty, they think something is under your door. If your garage door won't close, clean the photo eyes and your problem may be solved. If the photo eyes are clean but your door still won't shut, they could be out of alignment. Use a level to set them up evenly and your garage door should work again.
The tracks for your garage doors should be perfectly aligned. Your garage door not opening or closing could be a sign that your tracks are out of whack. If your garage door still moves, you may be able to fix it yourself. Just use a level and a mallet to beat your tracks back into alignment. If your garage door won't move at all, you'll need to call a professional to fix the tracks. This will keep you from making it worse and ensure the repair will last longer.
Blocked Garage Door Troubleshooting
Does your garage door close halfway then open back up? Something is likely blocking your door.
First, check the ground under your garage door. If there are any toys, tools, or large debris, clear it from your door's path.
If you don't see anything on the ground, check the tracks. Rocks, dirt and other debris could build up and prevent your doors from closing all the way.
Your garage doors have tension springs and cables to keep your door from opening and closing too fast. Once these parts break, your garage door can be dangerous to be around.
If you notice that your garage door slams shut, you need to fix the tension springs or cables. Keep your car and other valuables out of your garage until they're fixed. If your garage door won't open at all, it may be the torsion springs that are broken.
These are the springs that handle the weight of the heavy door. Broken springs and cables can cause serious injury. Get a professional to take a look as soon as possible to save yourself and others from getting hurt.
The limit range on your garage door tells it how far to move before it's shut. A high limit setting can make your door think it's hitting an object instead of the ground, which will make it open back up again. If your garage door won't open, your limit setting is too low.
