Garage Door Will Not Close: What It Is Doing Tells You Why
A garage door that will not close is almost always an opener refusing to run the door down, not a door that cannot move. The opener refuses for one of five reasons, and what the door does in the first two seconds tells you which. Three of the five cost nothing to fix, and the other two are a technician’s job that most pages online hand you a screwdriver for.
Need it shut tonightStand inside the garage where you can see the whole opening, make sure nothing is under the door, then press and hold the wall button until the door is all the way down. Let go early and it stops or climbs back up.
Most openers have that override built in, though LiftMaster and Chamberlain dropped it from units and boards made after February 2022, and it is safe for exactly as long as you are watching. Then phone (636) 577-1430.
Photo eyes and opener settings are the daily work of the garage door opener repair page, the trucks carry safety sensors and circuit boards, and the quote is free. A new pair of photo eyes runs $85 to $100 fitted on our opener troubleshooting guide’s price table, and opener repair across all faults runs $65 to $385.
What Is the Door Doing? That Tells You Why
Press the button once and watch. Match the first two seconds to the table, because each row points at a different part and a different person.
Swipe sideways to see the whole table.
| What the door does | Usual cause | Who fixes it | What it runs here |
|---|---|---|---|
| Will not start down at all; the opener’s light blinks and the motor clicks | Photo eyes blocked, dirty, out of line, or blinded by low sun | You, in about 10 minutes | Nothing. A failed pair is $85 to $100 fitted |
| Closes only while you hold the wall button, and a held remote will not do it | The eye circuit: the eyes, a stapled or chewed wire, or the terminal at the opener | You first; a technician if both lights stay dark | Nothing, or a wire repair inside the $65 to $385 opener range |
| Runs all the way down, touches the floor, and comes back up | Down travel set past the floor, or ice and grit under the bottom seal | You for the ice; a technician for the travel setting | Nothing, or a service visit |
| Stops short, leaves a gap, and stays there | Down travel set short, or the door binding in its last foot | A technician | A service visit; track work $5 to $400 if a rail is bent |
| Starts down, reverses part way, and the opener does not blink | The force limit tripping on a dragging roller, a dry track, or a tired spring | A technician | $65 to $385 on the opener side; a spring is its own job |
| Nothing from any button, no light, no click | Power, the lock button, or a dead opener | You for the outlet and the lock button | See the opener troubleshooting guide |
A blinking light is the opener naming the rule it tripped. On a LiftMaster or Chamberlain made since 2011, the up arrow flashing 4 times and the down arrow once means it felt an obstruction or a binding door. The units with a screen print it as error code 4-1. Every other count has its own meaning, listed in the garage door opener light blinking guide.
Older units flash the learn button 5 times every 10 seconds for the same fault. Rows 1 and 2 are the eyes, and they are the common ones. Rows 3 to 5 are travel and force, the two settings nearly every page online tells you to turn, and the two that stay off this page.
Is It the Photo Eyes? The 10-Second Wall Button Test
Most of the time, yes, and a held wall button proves it in 10 seconds.
Every home opener sold in this country since the start of 1993 has to carry a second safety guard besides its force sensing, under the federal rule 16 CFR 1211 and the UL 325 standard it adopts. On nearly every home opener that guard is the pair of photo eyes. Before it will close on its own, the opener confirms the beam is clear, every single time.
The standard also allows one exception, written for the night a sensor fails. The door may close with the eyes ignored only while a control hard-wired to the opener is held down, and only for as long as it is held. A remote cannot do it, because a remote sends one command and has no way to tell the opener you are still standing there.
That exception is the test. Stand with the whole opening in view, try to close the door with the remote held down, and then with the wall button held down.
One caveat before you read the result. Chamberlain’s support pages say openers and replacement logic boards made after February 3, 2022 no longer close on a held button, so on a new LiftMaster or Chamberlain a refusal proves nothing.
| What happens | What it proves | Next |
|---|---|---|
| The held wall button closes it; the held remote will not | The eye circuit is the fault and the opener is fine | The six checks below |
| Neither closes it, even held | Not the eyes, unless the opener is a LiftMaster or Chamberlain made after February 2022, which has no override. Otherwise force, travel, or something binding is tripping it | Rows 3 to 5 of the table above, then a call |
| Closes part way while held, then stops | Something is binding or blocking the door. The override does not bypass force, so holding harder does nothing | Hands off the door. Call |
| Closes fine from the remote, refuses from the app or the timer | An unattended close needs working eyes plus a warning beep, and on some models a separate light | A setting, not a fault |
Hold-to-close is a stopgap, not a repair. Closed that way, the door has no eyes watching for a child, a dog, or a car hood.
The Reddit thread Google ranks first for this search is a homeowner closing the door exactly that way. Fix it, or have it fixed, before the household gets used to it.
Six Checks on the Photo Eyes, No Tools
- Read both lights. One eye sits on each track, 6 inches or less off the floor. Expect two colors: amber or yellow where the beam starts, green where it lands. Steady on both sides means aligned. Blinking, dim, or dark on one side is your fault side.
- Clear the beam. The beam runs at floor level across the whole opening. A recycling bin, a coiled hose, a stroller wheel, a bag of mulch, or leaves blown in under the door all count.
- Wipe both lenses. Dry cloth, no spray. Garage dust lays a film on the lens that you cannot see until it is on the cloth.
- Shade the receiving eye. On a west- or south-facing door in St. Peters or Wentzville, low winter sun lands straight on the lens late in the afternoon and the eye cannot hear itself over the light. Hold a piece of cardboard over it and press the button. Should the door close, the eye needs a sun hood or the pair needs swapping sides, which the technician does.
- Nudge the bracket. Loosen the wing nut a quarter turn, aim the eye at its partner, and stop when the light holds steady. Tighten it without letting it drift.
- Look at the wire. A thin two-strand wire runs from each eye up the wall to the opener. A staple driven through it, a chewed spot, or a loose screw at the opener’s terminals shows as both lights dark. Both dark means stop here and call.
If both lights are steady and the door still refuses, the eyes are telling the truth and the opener is not. Pull the opener’s plug for 60 seconds.
That reboots the logic board and keeps every remote and every setting, so it costs nothing to try. The learn button is not a reset for this problem; holding it until its light goes out erases every remote and keypad and leaves the closing fault exactly where it was.
Reverses at the Floor, or Stops Short: Travel and Force
Two settings in the opener, chain-drive or belt-drive alike, decide the close. The travel limit tells it where the floor is, so it knows when to stop. The force limit is how hard it will push before it decides it has hit something and reverses.
A door that touches the floor and comes back up usually has its down travel set past the floor. The opener drives into the slab, reads the slab as an obstruction, and backs off.
The same thing happens on a January morning when the bottom seal has frozen to the concrete and a ridge of ice sits under the door. The January low here averages 22 degrees, and one freeze-thaw night will glue a damp rubber seal to the floor.
Clear the ice, warm the seal, and the door closes. Turn nothing up.
A gap that stays is the opposite: a down travel set short, or a door that binds in its last foot because a roller drags, a hinge is loose, or the galvanized steel track has a kink or a patch of rust from a humid summer. One that reverses part way with no blink is the force limit doing its job on that same drag.
The guide stops at the opener’s side panel for a reason the maker prints in capitals. Chamberlain’s own support page, the one Google ranks second for this problem, says as of October 2026 never raise the force beyond the minimum needed to close the door, and never use the force to make up for a door that binds or sticks.
Once the force has been turned up to cure a drag, the door no longer reverses on a 1-1/2 inch board laid on the floor. That board is the test the maker asks you to run every month.
Reading the five pages Google ranks highest for this search, we found that four of them walk you through raising that force a quarter turn at a time until the door closes. What they leave out is that the setting only means anything on a balanced door, and balance is the spring, which you cannot judge from the floor.
Where This Guide Stops, and What the Technician Does Instead
The guide is not for a door that will not open; that one has its own three checks in the garage door will not open guide. Nor is it for an opener dead to every button, which the garage door opener troubleshooting guide walks through outlet by outlet. The page covers an opener refusing to close, and nothing above adjusts a limit or a force. A door that opens by itself instead is covered in the garage door opens on its own guide.
When to call: both lights dark, a gap that stays, or a door that reverses with no blink. A technician on a will-not-close call takes these steps in a fixed sequence, because the sequence is what makes the fix hold:
- Balance test. Red cord pulled with the door down, then the door lifted halfway by hand. A balanced door stays within about 2 inches of where it is left. One that drops or climbs gets its spring set first, because no opener setting survives an unbalanced door.
- Binding check. Rollers, hinges, the steel track and the bottom seal, by hand, hunting for the drag the force limit was reacting to. A dry track or a worn roller gets fixed here rather than hidden under a higher force.
- Eyes and wiring. The beam, the brackets, the wire run, and the terminals at the opener. A failed pair comes off the truck.
- Travel, then force, to the maker’s spec. Travel first, because the two interact and Chamberlain says a change to one usually calls for a change to the other.
- The reversal tests. A 2×4 laid flat under the door, and the door must come back up on contact. Then the beam is broken by hand while the door is closing, and it must reverse again. Both are points on the 25-point inspection the garage door maintenance visit runs.
When I price one of these, the door goes up by hand before I touch the opener, because a spring that has given out shows up as an opener that refuses. Openers last 10 to 15 years, and the repair-or-replace table on the opener repair page puts a unit over 10 years old whose safety features no longer work on the replace side. One with no photo eyes at all, or made before 1993, is a conversation about replacing it, not repairing it, and the garage door openers page lists what we carry, starting near $375.
What Does It Cost in St. Charles?
The clear-and-aim checks cost nothing, and most calls about a door that will not close end there. When they do not, our opener troubleshooting guide’s price table puts a new pair of photo eyes at $85 to $100 fitted and opener repair across all faults at $65 to $385. Those figures match the garage door repair cost guide.
Emergency calls and free quotes are listed on the opener repair page, and its trucks carry safety sensors, circuit boards, remotes and drive gears. How long does it take? A sensor swap is usually one visit.
If a bent rail turns out to be the binding, track work runs $5 to $400 nationally and the garage door repair service page lists track repair as a same-day job.
