Short answer: If your garage door is stuck open at night, first check for anything blocking the safety sensors, then check power and the remote battery. If you hear a loud bang, see a broken spring, a loose cable, or a door hanging crooked, do not force it. Lock the door from the garage into your home, move valuables out of sight, and call a licensed, bonded and insured technician at (480) 690-3344.
A garage door stuck open is one of the most stressful problems a homeowner can face after dark. The garage is often the easiest way into the house, and an open door shows every passerby your vehicles, tools and holiday packages. The good news is that many causes are simple to check, and even when the problem needs a technician, you can make your home much safer while you wait.
This guide walks you through what to check, what to leave alone, and how to secure the space tonight. When it is time for help, our emergency garage door repair service covers Phoenix, Tempe and the East Valley.
Why a Garage Door Gets Stuck Open
A garage door stuck open is almost always reacting to one of a handful of problems. Some are safety features doing their job. Others are parts that have failed under load.
1. Blocked or misaligned safety sensors
The two small photo eyes near the floor stop the door from closing when something is in the way. A trash bin, a leaf, dust on the lens, or a bumped bracket can make the opener think something is in the path. The door goes down a few inches and reverses, leaving the garage door stuck open with the opener light blinking.
2. A broken torsion or extension spring
Springs carry the weight of the door. When one breaks, the opener cannot control the door, so it may stop, strain, or refuse to move. Many homeowners hear a sharp bang in the garage before this happens.
3. A snapped or slipped cable
Cables work with the springs to lift and lower the door evenly. A frayed or loose cable can leave a garage door stuck open and hanging crooked. This is one of the most dangerous situations, so keep everyone away from the door.
4. The door is off its track
If a roller jumps out of the rail, the door can jam partway. You may see a gap between the door and the track or a panel that looks twisted. Our off-track garage door repair page explains why this happens.
5. Power, remote or keypad problems
A tripped breaker, a power outage, or a dead battery in the remote or keypad can leave a perfectly healthy door stuck open. These are the easiest causes of a garage door stuck open to rule out first.
How to Tell What Is Wrong With a Garage Door Stuck Open
Use this table to match what you see with the most likely cause, and to decide whether it is something you can safely check yourself.
| What you see | Likely cause | Safe to handle yourself? |
|---|---|---|
| Door reverses or blinks, sensors lit unevenly | Blocked or misaligned safety sensors | Yes: clean and realign |
| Opener hums, door does not move | Broken spring or disconnected trolley | No: call a technician |
| Door hangs crooked or a cable is loose | Snapped or slipped cable | No: do not touch it |
| Rollers out of the rail, door tilted | Door off track | No: call a technician |
| Nothing happens at all | Power, remote or keypad battery | Yes: check breaker and batteries |
7 Steps to Take When Your Garage Door Is Stuck Open at Night
1. Keep people and pets clear
Before you touch a garage door stuck open, make sure no one is standing under the door or near the springs.
2. Look at the springs and cables from a distance
Use a flashlight. If your garage door is stuck open and you see a gap in a spring, a loose or frayed cable, or the door hanging unevenly, stop here and call for help.
3. Check the safety sensors
Remove anything in the beam path, wipe both lenses with a soft cloth, and make sure both sensor lights are steady. Then try the wall button again.
4. Hold the wall button down
On most openers, pressing and holding the wall button bypasses the sensors and lowers the door slowly. Keep watching the door the whole time and let go if anything looks wrong.
5. Check power and batteries
Make sure the opener has power and the breaker has not tripped. Replace the batteries in your remote or keypad.
6. Use the emergency release only if it is safe
If the springs and cables look fine and the power is out, you can use the release cord and lower the door by hand. Read our guide to the garage door emergency release cord before you pull it. Never pull it on a door with a broken spring.
7. Secure your home if the door stays open
Lock the door between the garage and the house, take remotes out of parked vehicles, move valuables and packages inside, and turn on exterior lights.
What Not to Do With a Garage Door Stuck Open
- Do not force the door down with a broken spring. The door can weigh well over 100 pounds and can fall without warning.
- Do not loosen or adjust spring hardware. Springs hold dangerous tension. Leave garage door spring repair to a trained technician.
- Do not tape over or unplug the safety sensors. They protect children, pets and vehicles.
- Do not keep pressing the remote. If the opener is straining, repeated tries can burn out the motor or gears.

Why This Happens More Often in Arizona
Valley heat is hard on garage doors. Summer temperatures inside a closed garage can climb far above the outdoor reading, which dries out rollers and weakens springs over time. Dust storms coat sensor lenses, and fall and winter temperature swings make metal parts expand and contract. That is why so many East Valley homeowners find a garage door stuck open in November and December, right when holiday deliveries pile up on the driveway.
It is also smart to check whether your opener model has an open safety recall on the CPSC recalls page, especially if it is more than ten years old.
