A garage door not opening usually fails in one of three places: the opener cannot start a cycle, the door is locked or bound so the motor gives up, or a spring has broken and the panel will not rise. The right first step depends on what you hear and whether the door moves at all by hand.
Calls from Ponte Vedra often start the same way. The wall button clicks, the light comes on, and the door stays down. Sometimes the door lifts two inches and stops. LiftUp Garage Door Services repairs openers, springs, and tracks. Call (904) 503-6273 if a car is trapped or the door is sitting partway open. The checks below help you describe the failure before a visit.

Sort the failure by what you see
Write down three facts before you start swapping batteries. Does the opener light turn on? Does the trolley move on the rail? Does the door twitch and then stop?
No light and no sound usually means power: a tripped outlet, a GFCI in the garage, or an unplugged unit after someone used that receptacle for a charger. Light on, no trolley movement, points to the wall button, the remote, the logic board, or a safety circuit that is holding the door. Trolley moves but the door stays put often means the trolley is disconnected from the door arm, or the release cord was pulled and never re-latched.
A door that rises a few inches and drops back is rarely an electrical problem. That pattern is lost spring tension or a cable off the drum. Keep using the opener in that state and you will smell a hot motor before the door ever clears the car.
Power, remotes, and the wall button
Start with power because it is the only check that does not put you under a moving door.
- Confirm the opener is plugged in and the outlet has power. Plug a lamp into the same socket.
- Press the GFCI reset button if the garage outlets are protected. A trip after a storm is common.
- Replace the remote battery, then stand under the opener and use the wall control. If the wall button works and the remote does not, the remote or its programming is the issue, not the door.
- Look at the opener’s LED. A steady blink pattern is often a diagnostic code in the manual on the unit’s housing. Photograph it.
Vacation locks and lock switches on the wall control stop the door from opening even when power is fine. If someone enabled the lock so kids could not cycle the door, the remote will click and do nothing. Flip the lock off and try again.
If the motor runs and the chain or belt moves but the door does not, the emergency release is probably open. With the door fully closed, pull the cord toward the door to re-engage the trolley, then run a cycle. Do not re-engage it while the door is open unless you know the springs still hold the door. Our garage door opener repair page covers motor, gear, and remote faults that survive these basic checks.

Locks, photo eyes, and travel limits
Photo eyes stop a door from closing. They do not, by themselves, stop a door from opening. People still chase sensors for an opening failure because the opener light blinks. If the door will not go up, look elsewhere first. If it opens and will not come down, then clean the lenses, confirm both sensors have power, and make sure the brackets were not kicked out of alignment.
A slide lock on the vertical track is a frequent “dead door.” It is a metal bar that pins the door to the track. If it is engaged, the opener strains and may reverse. Check both sides. Some older doors also have an outside lock cylinder that throws a bar inside. If you never use that lock, the bar can still be half-thrown after a bump.
Travel limits tell the opener where “open” and “closed” are. After a power surge or a partial gear failure, the opener may think the door is already open and refuse to move. Resetting limits is reasonable if you have the manual and the door is balanced. It is a poor idea if the door is heavy or crooked. Wrong limits can drive the door into the header or try to crush the bottom seal.
Springs and cables that block the lift
Look above the door. A torsion spring with a visible gap in the coil has broken. Extension springs that hang loose along the horizontal track have failed or come off their pulley. In both cases the opener is being asked to lift the full door. Most units will try once or twice, then stop to protect the motor.
Cables should run from the bottom bracket straight up to the drum. A cable that is slack, frayed, or wrapped beside the drum instead of in the grooves will let one side lag. The door may open a foot and twist. Stop the cycle if you see that. Twisting bends the track and can pull hinges off the panel.
Spring and cable repairs are not weekend projects. The spring replacement process uses winding bars and a balance test. If the door is also noisy or has been getting heavier for weeks, say so when you schedule. A tech can bring rollers and a cable set instead of discovering the extra parts on site.
For a door stuck open before rain, or a spring that broke overnight, emergency garage door repair is the faster path. The longer guide on when a garage door problem is an emergency explains which failures can wait until morning and which should not.
When a manual lift is safe
Lifting by hand is reasonable only when the springs are intact, the door is straight, and you can disconnect the opener with the door fully closed. Pull the red cord, then raise the door slowly. It should feel manageable and stay up. If it feels like the full weight of the door, stop. You are holding a panel that can fall.
Never prop a half-open door with a ladder or a broom. People do this to get a car out, and the prop slips. If you need the car and the door will not move safely, call. Same-day service is set up for exactly that morning.
While you wait, leave the opener unplugged if it keeps trying to run on its own. A motor that cycles against a locked or broken door will burn the board or the gear. Clear the area under the door so nobody walks through while the panel is unpredictable.
The CPSC garage door safety guidance is worth two minutes if children use the garage. Automatic reverse and photo eyes matter, but they do not protect anyone from a door with a broken spring.
FAQ
Tell us what the door does
A garage door not opening is faster to fix when the symptom is specific. Call LiftUp Garage Door Services at (904) 503-6273 or use the contact form. Say whether the opener light is on, whether you heard a bang, and whether the door is fully closed or stuck partway. If you can do it safely, a photo of the spring and both cables helps the tech arrive with the right parts.
