Why Won't My Garage Door Open or Close?

Last updated: October 8, 2026 · Written by the Swift Lift Garage Door team, Atlanta, GA

Short answer: a garage door usually won't open because of a dead remote battery, no power to the opener, or a broken spring. It usually won't close because the safety sensors near the floor are blocked, dirty or out of line. Batteries, power, lock mode and sensors are safe to check yourself. Springs, cables and off-track doors are not.

Safety first: if the door is heavy, crooked, or only rises part-way, stop pressing the button — running the opener against a failed spring or cable causes more damage and can be dangerous. Keep people and cars clear of the door and call a professional.

What is your door doing?

Match the symptom to the most likely cause, then jump to that section.

• Wall button works, remote doesn't → remote battery or lock mode
• Nothing happens at all, no lights or sound → no power to the opener
• Loud bang, then the door is very heavy or lifts only a few inches → broken spring
• Door hangs crooked, or a cable is loose → snapped cable
• Door is jammed at an angle, or a roller is out of the rail → off the track
• Door starts to close, then goes back up → safety sensors or travel limits
• Motor hums or runs, but the door doesn't move → worn opener parts

1. Dead remote or keypad battery

If the wall button works but the remote doesn't, the cause is almost always a dead remote battery or a remote that lost its programming. The door, springs and opener are fine. Replace the battery first (most remotes use a CR2032 coin cell). If a new battery doesn't help, reprogram the remote with the "Learn" button on the opener motor.

2. No power to the opener

If nothing happens and the opener shows no lights, it has no power. Check that it is plugged in, then test the ceiling outlet with a lamp or phone charger. In Atlanta this often follows a thunderstorm: a GFCI outlet elsewhere in the garage has tripped, or a breaker has. Press the outlet's "Reset" button and check the breaker panel. If the outlet has power and the opener is still dead after a storm, a surge may have damaged its circuit board.

3. Broken torsion spring

If you heard a loud bang from the garage and the door is now far too heavy or lifts only a few inches, a spring has snapped. This is the most common reason a door suddenly stops opening. Look at the spring on the bar above the door: a broken one shows a visible gap of an inch or two in the coil. Do not keep pressing the button and do not try to replace it yourself — the spring system holds enough tension to cause serious injury. Georgia humidity rusts springs and shortens their life, so this is a frequent call here. See spring replacement →

4. Snapped or frayed cable

If one side of the door sits lower than the other, or a steel cable hangs loose beside the track, a lift cable has failed. The door is unbalanced and can drop or twist. Leave it where it is, keep clear, and don't run the opener. See cable repair →

5. Door off the track

If the door is jammed at an angle or a roller has popped out of the metal rail, it is off-track. This usually happens after the door is hit by a car or closes on something. Forcing it with the opener bends the panels and the track, which turns a repair into a replacement. See off-track repair →

6. Misaligned or dirty safety sensors

If the door opens normally but won't close, or starts down and goes back up, the two photo-eye sensors near the floor are the first thing to check. Each has a small light; both should be steady, not blinking. Wipe the lenses, remove anything in the beam's path, and gently turn a blinking sensor until its light holds steady. Low afternoon sun shining straight into one sensor can cause the same problem — if the door only refuses to close at a certain time of day, shade the sensor and try again.

7. Travel or force limits need adjusting

If the sensors are clean and lined up but the door still reverses just before the floor, or stops short of fully open, the opener's travel or force settings have drifted. Temperature swings and a door that has become harder to move both cause this. It is a quick adjustment for a technician, and it is worth having the door's balance checked at the same visit, because an opener that needs more force is often hiding a tired spring.

8. Lock mode or vacation lock is on

Many wall consoles have a "Lock" button that turns off all remotes and keypads. If the remotes stopped working suddenly but the wall button still works, press and hold the Lock button for a few seconds to switch it off. A blinking light on the wall console usually means lock mode is on.

9. Worn opener gear, trolley, or logic board

If the motor hums or runs but the door doesn't move, first check that nobody pulled the red release cord — the door may simply be disconnected from the opener. If it is connected, an internal part such as the drive gear, trolley or circuit board has worn out. A technician can tell you quickly whether a repair or a new opener makes more sense.

How do I open my garage door by hand if my car is trapped?

Only do this when the door is fully closed and the spring is not broken. Pull the red release cord hanging from the opener rail straight down to disconnect the door, then lift from the bottom with both hands. A healthy door lifts with moderate effort and stays up on its own. If it feels extremely heavy or won't stay up, stop and lower it — the spring is broken and the door's full weight, often 150 pounds or more, is on you. Never pull the release cord while the door is open; with a broken spring it can slam shut.

What can I check myself, and when should I call a professional?

Remote batteries, power to the opener, lock mode and dirty or misaligned sensors are safe to check yourself. Anything involving springs, cables, or an off-track door stores serious tension and should be handled by a trained, insured technician. If your car is stuck or the door won't close at night, our Atlanta line is open 24/7. See 24/7 emergency repair →

Frequently asked questions

Works on the wall button but not the remote — why?

Usually a dead remote battery or a remote that needs reprogramming. If the wall button works, your door, springs and opener are fine — start with a new battery.

Door opens a few inches then stops?

That's the classic sign of a broken torsion spring — the opener can't lift the full weight alone. Stop using the door and call a professional; don't force it.

Door won't close all the way?

Most often the floor-level safety sensors are misaligned or dirty, or the travel limit needs adjusting. Clean the lenses and confirm steady lights; if it still reverses, have it adjusted.

Is it safe to open a garage door with a broken spring?

No. Without the spring the opener and you are lifting the door's full weight, and the door can fall without warning. Leave it closed, don't use the opener, and have the spring replaced before using the door again.

Why did my garage door stop working after a storm?

Most often a GFCI outlet or breaker tripped, so the opener has no power. Reset both. If the outlet has power and the opener is still dead, a power surge may have damaged the opener's circuit board, which needs a technician.
