Garage Door Opens then Reverses: Sixty-second triage
Work down the list. Everything marked safe takes a minute and no tools; everything marked otherwise is under spring or opener load, and the honest answer is that you should not be the one touching it.
Every cause on this page, and whether it is yours to check

Garage Door Opens Then Reverses is best traced from the most likely cause to the least likely, using the visible behavior before any part is touched.
01Opens then Reverses Garage Door: Up-force setting too low for the door's real weight
For Garage Door Opens Then Reverses, this check matters because as springs age they lift less, the door effectively gains weight, and the opener reads normal drag as an obstruction and backs off. Raising the force is the wrong answer; rebalancing the door is the right one.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
02Opens then Reverses Garage Door: Up-travel limit set short
For Garage Door Opens Then Reverses, this check matters because the opener reaches what it believes is fully open before the door is, senses continued resistance and reverses. A limit reset takes minutes for a technician and is easy to get wrong from a ladder.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
03Opens then Reverses Garage Door: Door binding in the tracks
For Garage Door Opens Then Reverses, this check matters because dry rollers, a tight track or a bent section create a stiff spot part way up. The opener hits it, calls it an obstruction and reverses at the same height every time - the repeatability is the tell.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
04Opens then Reverses Garage Door: One spring of a pair has broken
For Garage Door Opens Then Reverses, this check matters because half the counterbalance is gone, so the door is roughly twice the weight the opener expects. It will often lift a foot or two and then give up. Do not keep cycling it.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
05Safety reversal test being triggered by a real obstruction
For Garage Door Opens Then Reverses, this check matters because check that nothing is stacked against the door on the inside and that the tracks are clear before assuming an electronic fault.
Safe to check yourself, with the door closed and the opener unplugged.
06Failing travel or RPM sensor module
For Garage Door Opens Then Reverses, this check matters because the opener counts revolutions to know where the door is. When the counter stutters, the unit believes it has stalled and reverses. Part replacement.
Do not attempt this yourself. It is under spring or cable load and it injures people every year - this one is a licensed-technician job.
Opens then Reverses Garage Door: What to do about it
How urgent is this, honestly?
For Garage Door Opens Then Reverses, not an emergency, and anyone who tells you otherwise is selling you an after-hours rate. 1 of the 6 causes here are things you can check yourself in the next few minutes, and a meaningful share of these resolve without anybody being dispatched. What it is worth doing is not ignoring it. Garage door faults are progressive: the thing that is currently an inconvenience is attached to a component that is wearing, and the cost of the eventual repair goes up rather than down while you get used to working around it.
Work through these first, in this order
For Garage Door Opens Then Reverses, there is one thing on this list you can check safely yourself, with the door closed and the opener unplugged, and they are ordered here by how often they turn out to be the answer rather than by how interesting they are. Start with safety reversal test being triggered by a real obstruction. None of these needs a tool you do not already own, none takes more than a couple of minutes, and each one you rule out makes the phone call shorter and the price band tighter if you do end up needing one. The reason to do them in order is that the common causes are also the cheap ones, and diagnosing from the expensive end is how people end up replacing a working opener.
What you should not touch
For Garage Door Opens Then Reverses, 5 of the causes on this page are genuinely not a homeowner job: up-force setting too low for the door's real weight; up-travel limit set short; door binding in the tracks. That is not us protecting our own work. A torsion spring stores enough energy to kill and releases all of it the moment a winding bar slips; a lift cable under load will cut through a hand; a door that has left its track is carrying its weight unevenly and can drop without warning. The tooling matters as much as the technique and the technique is not obvious from a video. Everything else on this page - the checks above, the lens cleaning, counting diagnostic flashes, testing balance with the opener disconnected - is safe. These are not, and the injuries are severe rather than inconvenient.
What a technician will actually do
For Garage Door Opens Then Reverses, the visit follows the same order as this page, deliberately: cheap causes ruled out before expensive ones are quoted. The checks you have already run get repeated - not because we doubt you, but because "I cleaned the lenses" and "I cleaned the lenses and both LEDs then glowed steady" are different pieces of information. Then the components come into it in ascending order of cost, which for this fault means working toward up-force setting too low for the door's real weight rather than starting there. You get a written figure before any work begins. If something else turns up once a cover is off, the honest thing is to stop and re-quote, and that is what happens rather than a bigger number appearing on the invoice at the end.
If none of it explains what you are seeing
For Garage Door Opens Then Reverses, then it is probably two things at once, which is more common than people expect because garage door components wear in groups. A spring at the end of its cycle life has usually been dragging on a cable for months; a door slightly out of balance puts load on an opener that then fails in a way that looks unrelated; a track bent in an old impact produces a binding that presents as a completely different fault a year later. This is also why a diagnosis that explains most but not all of what you are seeing is worth pushing on: "the sensors were misaligned" is a complete answer only if realigning them actually fixed it. Describe everything you have noticed, including the things that seem unrelated - the noise last month, the one time it stopped halfway - because that is usually where the second fault is hiding.
Stopping it happening again
For Garage Door Opens Then Reverses, most repeat failures on this fault come from one of three places. The repair addressed the symptom and not the cause, which is why a competent visit finds out why rather than only what. The door was left out of balance, so whatever was compensating for it carries on compensating and fails again on schedule - the balance test takes fifteen seconds with the opener disconnected and it is the single most useful thing a homeowner can learn. Or a component was replaced without its pair: springs, cables and rollers all work in matched sets, and a new one working against a fatigued one is a repair with a countdown attached. A service interval of one to two years on a door running four to six cycles a day catches all three before they become call-outs.
What it costs to put right
For Garage Door Opens Then Reverses, editorial California planning range: $150–$450 depending on the failed component for opener repair across California, and where a specific job lands inside that band comes down to which of the causes above turned out to be yours, the door's weight and size, and whether anything failed alongside it. The two things that reliably move a quote in the wrong direction are cycling a broken door repeatedly before the visit, which turns small repairs into large ones, and accepting a figure without asking what it includes. Ask whether cables are in it, what cycle rating the springs are, what the warranty covers on parts, and whether the trip is included - four questions that turn a spread which looked like price into a spread that is mostly specification.
What to tell whoever else is in the house
For Garage Door Opens Then Reverses, worth thirty seconds, because the person who causes the second problem is usually not the person who found the first. Tell them what the door is doing and that it should not be operated until it is looked at - particularly not repeatedly, which is the instinct. Tell them not to pull the red emergency release handle if the door is open: that disconnects the trolley from the opener, and on a door with a failed spring the opener may be the only thing holding it up. Keep vehicles and bicycles out from under it, and if there are children in the house, keep the wall control out of reach for the day. None of that is alarmist - a garage door is the heaviest moving object most households own, and the failures on this page are precisely the ones that change how it behaves.
The parts this fault actually involves
For Garage Door Opens Then Reverses, four components do the work on any garage door and knowing which one this fault sits in makes the rest of the page easier to read. The springs counterbalance the door's weight - they, not the opener, are what makes a 300lb door liftable by hand - and they are rated in cycles rather than years. The cables transfer that counterbalance from the spring to the bottom of the door, in matched pairs, and they fail from the inside where you cannot see it. The track and rollers guide the door's path and tolerate very little misalignment before they bind. And the opener guides an already-balanced door and provides the safety systems - photo-eyes, auto-reverse, force limits - that stop it closing on something. The causes flagged as professional on this page sit in the first two of those, which is why they are flagged.
If you have already tried something
For Garage Door Opens Then Reverses, say so on the call, and be specific about what happened rather than what you did. "I cleaned the lenses" and "I cleaned the lenses and both LEDs then glowed steady but it still reversed" are different pieces of information, and the second one eliminates a cause that the first one does not. The things worth mentioning that people usually leave out: anything that changed recently, including work done by somebody else; whether the behaviour is consistent or intermittent, because intermittent points somewhere quite different; whether it is worse at a particular time of day, which on sensor faults is often the whole answer; and anything you heard in the weeks before it failed. A door rarely fails without warning - it fails without the warning being recognised.
What this does to the rest of the door
For Garage Door Opens Then Reverses, nothing on a garage door fails in isolation for long, and this fault is no exception. While it is unresolved, the load that component was carrying goes somewhere else - usually onto the opener, which was designed to guide a balanced door rather than to lift an unbalanced one. That is why a fault left for a few weeks so often ends with two invoices instead of one, and why the second one is for a motor that was working perfectly before. The practical version of this is that the cost of the eventual repair goes up rather than down while you work around it, and the components that get damaged in the meantime are usually more expensive than the one that started it. That is the whole argument for dealing with it this week rather than next month, and it is arithmetic rather than urgency.
Getting a straight answer on the phone
For Garage Door Opens Then Reverses, three answers diagnose the majority of these before anyone is dispatched. What it sounds like - a single bang, a grinding scrape, a motor humming with no movement and a click with nothing are four different faults. Where in its travel it stops - six inches off the floor, halfway, or just before it seals, each pointing somewhere different. And what the lights are doing, because most openers flash a diagnostic code before they give up and counting the flashes usually narrows the fault to a single component. Add the door's rough size and whether it is insulated and you have enough for a real price band. None of that is a form; it is a two-minute conversation, and it is the difference between a quote and a diagnostic fee.
