Garage Door Won't Open or Close? What to Check
A garage door that won't open or close can come down to something simple — a power issue, a remote or wall control, or a blocked safety sensor. It can also involve an opener failure, a broken spring, a cable or track problem, or another mechanical issue. The symptom on its own doesn't tell you which, so this guide walks through what the door is doing, what's safe to check, and when to stop and get help.
If you'd rather skip ahead, you can request help or call (931) 277-6500.
First, look at what the door is doing
These are starting points, not diagnoses. The same behavior can have more than one cause.
- Nothing happens when you press the buttonOften points first toward power, controls or the opener — though not always.
- Opener runs but the door doesn't move normallyCan involve the opener or the door's mechanical parts.
- Door starts closing, then reversesObstruction or safety sensor issues are one possible cause.
- Door opens only partwayCan relate to the opener, door balance, springs or tracks.
- Door is crooked or unevenMay involve cables, tracks or other components under tension.
- Door seems stuck or off its normal pathCould involve rollers or tracks. Avoid forcing it.
- A loud bang came before the problemCan be consistent with a spring problem.
- The door can't be lifted normallyVery heavy doors may point toward a spring or balance issue.
Safe things a homeowner can check
These are low-risk observations. None involve taking anything apart or touching parts under tension.
- Confirm the opener has power — is its light working, and is it plugged in with the outlet or breaker on?
- Try the wall control. If it works but the remote doesn't, the remote may be the issue.
- Replace remote or keypad batteries if they could be low.
- Make sure nothing is sitting in the doorway or under the door.
- Look at the photo-eye sensors near the floor on each side for dirt, a blocked lens, or one that's obviously knocked out of position.
- From a safe distance, look for visible damage — a gap in a spring, a loose cable, a bent track, or a door hanging unevenly.
Please don't take the opener or door apart, adjust springs, cables or bottom brackets, or force a stuck or crooked door.
When the door starts down and reverses
Openers are designed to reverse when something is in the door's path. Something in the doorway, or a safety sensor that's blocked, dirty or knocked out of line, is one possible cause. Clear the doorway and check the sensor area visually.
If the door keeps reversing after you've ruled out obvious obstructions, the opener or door may need a closer look — see garage door opener repair. The safety system should never be bypassed or disabled.
When the opener runs but the door doesn't move normally
If you hear the motor but the door doesn't move, stops partway, or moves unevenly, the opener may be at fault — but the door's mechanical parts can also cause this. It's worth having both looked at rather than assuming it's the opener. Our pages on opener repair and garage door repair explain more.
Loud bang, heavy door, or a door that won't lift
These symptoms can be consistent with a spring problem, although they don't prove it on their own. Springs balance most of the door's weight, so a failure can make the door feel very heavy and keep the opener from lifting it.
Springs store a lot of energy, and adjusting or replacing them without the right tools and training can cause serious injury. See garage door spring repair for what a professional repair typically involves.
Crooked, jammed or off-track door
A door that's hanging unevenly, has a visible cable problem, or has moved out of its normal track can involve parts under substantial tension. Avoid forcing it or running it again and again — that can make the damage worse or cause the door to shift suddenly.

When to stop troubleshooting
It's a good time to stop and request help if you notice any of the following. This isn't a complete list — if something feels wrong, it's reasonable to stop.
- A spring that looks broken or separated
- A loose, frayed or displaced cable
- A crooked or unstable door
- A door visibly off its track
- A door that falls or won't stay in position
- Significant impact damage
- Repeated abnormal movement
- Anything that would mean removing or adjusting high-tension parts
If the door is stuck open or unsafe to use, see emergency garage door repair.
Repair or replacement?
A door that won't open or close doesn't automatically need replacing. Depending on the cause and the condition of the rest of the system, a repair may solve the problem. When there's substantial damage, broad deterioration, or repeated problems, it can be worth weighing garage door replacement.

Frequently asked questions
Why won't my garage door open even though the opener has power?
Power to the opener is only one part of the system. A remote or wall-control problem, a safety sensor issue, an internal opener fault, or a mechanical problem with the door itself — such as a spring, cable or track issue — can all keep a door from opening. If the simple checks don't explain it, the door and opener usually need to be looked at in person.
Why does my garage door start closing and then go back up?
Openers are designed to reverse when they sense an obstruction, so something in the doorway or a blocked or misaligned safety sensor is one possible cause. If the doorway and sensor area are clear and the door keeps reversing, the opener or door may need evaluation. Safety sensors should never be bypassed or disabled.
Can a broken spring keep a garage door from opening?
Yes, it can. Springs counterbalance most of the door's weight, so when one fails the door can feel very heavy and the opener may not be able to lift it. A loud bang followed by lifting trouble is a common sign, though only an in-person look can confirm the cause. Springs are under high tension and should be left to a professional.
Should I keep using a garage door that's crooked or off track?
It's best not to. A crooked or off-track door can involve cables, rollers and other parts under tension, and repeatedly running it or forcing it can make the damage worse or cause the door to shift unexpectedly. Stop operating it and request an evaluation.
Does a garage door that won't open always need to be replaced?
No. Many causes involve a single component that can be repaired. Replacement is usually worth considering only when there is substantial damage, broad deterioration, or repeated problems across the door system.
