Reversing is not a malfunction — it is the operator finding more resistance than it expects and backing off, exactly as it is built to. The job is working out whether the resistance is real, and this page shows you how to tell.
We measure the actual closing force rather than guessing at the dial
A gate that has aged gets its force re-commissioned to the gate it is now
Real resistance gets fixed at the hinge, track or post — not tuned out at the board
Security risk
The gate ends up open every time, so the property is not secured — and unlike a gate that simply will not move, this one is repeatedly driving itself into whatever is stopping it.
Check these first — before you call anyone
Some causes of gate reverses when closing you can resolve yourself in minutes. We would rather you found one than paid us to.
1
Note exactly where it reverses
Run the gate and watch. A consistent reversal point means a physical cause at that point — or a photo-eye the leaf passes there. A reversal point that moves suggests an intermittent electrical or sensor fault. Tell us which, and the visit gets much shorter.
2
Close the gate by hand
With the operator released, push the gate closed. It should move smoothly with one hand all the way. Increasing heaviness near the reversal point means the operator is correctly detecting real resistance, and the fix is mechanical.
3
Look for a scrape arc on the ground
A curved scuff mark on the driveway under a swing gate is proof the leaf is grounding. That is a sagging gate, and the reversal is a consequence rather than the fault.
4
Check whether heat makes it worse
If it closes cleanly in the morning and reverses in the afternoon, the cause is more likely a capacitor or battery that cannot deliver full torque when hot than anything mechanical.
What not to do
Do not increase the obstruction-force setting to stop the reversing. That setting is entrapment protection — it is what makes the gate stop instead of crushing what it meets.
Do not disconnect the edge sensor or photo-eye to get a clean close.
Do not keep cycling the gate. Each reversal is the operator driving the gate into real resistance and then reversing under load, which wears the motor, the gearbox and the gate.
Do not shim or wedge the gate to stop it grounding — that transfers the load into the hinge that is already failing.
Checked all that and it is still gate reverses when closing?
Reversing and refusing to move are different signals
A gate that will not begin to close is being blocked by a safety input before it starts — normally a photo-eye reporting a clear obstruction. A gate that begins closing and then reverses got further: it started, met resistance partway, and its obstruction detection decided something was in the way.
That difference matters because it points at different hardware. The first is a sensor question. The second is a force question, and force is measured by the operator watching how hard its own motor is working. So the diagnosis is about what changed between the gate the operator was taught and the gate it has now.
Why a healthy gate starts reversing without anything being in the way
Obstruction force is commissioned against the gate as it is on the day of installation. Over the following years the gate changes: a swing leaf settles on its hinges, a slide gate’s rollers wear, a chain stretches, grit builds in a track, hinges dry out, and in this region a post moves with the clay it is set in. Each adds a little resistance.
None of these on its own is enough to stop a gate. Together they lift the effort required past the threshold the operator was taught, and the operator does the only thing it can: it concludes something is in the way and reverses. Nothing is in the way, and nothing has failed — the gate has simply got stiffer than its own settings expect. That is a real fault with a real fix, and the fix is not turning the dial up.
What causes it, most likely first
Each of these looks different at the gate. The “how to tell” line is what separates it from the one above.
Genuine resistance from track, roller, hinge or post wear
most common
How to tell
Release the operator and close the gate by hand. It should move smoothly with one hand through its whole travel. If you feel it getting heavier at the point where the operator gives up, the resistance is real and the operator is right.
The fix
Fix the mechanical cause — clear or repair the track, replace the worn roller, reset the dropped hinge, address the post. Then re-commission the force against the repaired gate.
Obstruction force set for a gate that no longer exists
most common
How to tell
The gate pushes freely by hand through its entire travel and still reverses. Very common on installations five years and older, and on gates where a heavier leaf was fitted without the operator being re-commissioned.
The fix
Re-commissioning the force and travel settings against the gate as it is today — within the limits the safety standard allows, never simply raised until the symptom stops.
Photo-eye triggering partway through the closing travel
commonYou can often fix this
How to tell
Watch the gate as it reverses and note where it is when it changes direction. If it reverses at the same point where the leaf passes the beam, the sensor is being clipped by the gate itself — usually because a housing was knocked or a gate has sagged into the beam path.
The fix
Repositioning the sensor, or correcting the sag that has brought the gate into the beam.
Edge sensor making intermittent contact
common
How to tell
The reversal point moves around rather than being consistent. An edge sensor with a damaged strip or a fatigued cable makes and breaks contact as the gate moves and vibrates.
The fix
Edge sensor or cable replacement. These are mounted on the moving leaf and flex every cycle, so they are a genuine wear item.
Gate grounding on a driveway that has heaved or settled
common
How to tell
Swing gates especially. Look for an arc-shaped scrape on the driveway surface. The gate clears the ground for most of its travel and touches down near the closed position, which is exactly when the reversal happens.
The fix
Re-squaring or raising the leaf, resetting the hinge, or addressing the slab. Common on concrete over expansive clay.
Failing capacitor or weak battery misread as an obstruction
less common
How to tell
The gate reverses more readily when hot, or later in the day, and manages a clean close first thing. An operator that cannot deliver full torque looks — from the board’s perspective — exactly like a gate that has become hard to move.
The fix
Capacitor or battery replacement. Worth ruling in before force settings are touched, because adjusting force to compensate for a dying capacitor hides a fault that is about to get worse.
Repair, or replace?
Almost always repairable, and usually mechanically. The important judgement is honesty about which of the two main causes you have: a genuinely stiff gate needs a mechanical repair, and a correctly-working gate whose settings have aged needs re-commissioning. Turning the force up addresses neither and removes a safety function while it does it.
Usually a repair
Track clearing, roller and chain replacement
Hinge resetting and re-squaring a sagging leaf
Force and travel re-commissioning within standard limits
Photo-eye repositioning and edge sensor replacement
Capacitors and batteries
Sometimes a replacement
An operator under-specified for the gate’s weight, where reversing is the specification showing itself rather than a fault
An edge sensor type no longer manufactured, where a current equivalent is the sensible upgrade
Why this happens in Dallas–Fort Worth
Expansive clay makes this a seasonal complaint
Gates in Dallas–Fort Worth get measurably stiffer through late summer. The Blackland Prairie clay much of the metroplex sits on shrinks hard in a long dry spell, posts move with it, and a gate that was square in April is very slightly out of square by September. Driveways over that clay heave and settle on the same cycle.
The result is a wave of reversing gates that have nothing in the way and nothing broken — they have simply moved outside the settings they were commissioned to. It is also why we re-check the posts and the ground before we touch a force setting on a gate that has behaved perfectly for years.
My gate starts to close then opens again, but there is nothing in the way. Why?
The operator measures how hard its motor is working and reverses if that exceeds what it was taught. If the gate has become stiffer over the years — worn rollers, a settled hinge, a post that has moved — the effort now exceeds the old threshold even with nothing in the path. The fix is to repair the stiffness and re-commission the settings.
Can you just turn the force up so it closes?
We will not, and you should be wary of anyone who offers to. That setting is what makes the gate stop rather than crush a car, a pet or a person. Raising it to mask a mechanical fault removes the protection and leaves the fault to get worse. Re-commissioning within the standard’s limits is a different thing, and that we will do.
It reverses at the same spot every time. What does that tell you?
That the cause is at that spot. Either something physical is there — a fouled section of track, a roller reaching its worn point, the leaf grounding on the driveway — or the gate is passing a photo-eye whose housing has been knocked into the leaf’s path. A consistent reversal point is the most useful clue you can give us.
Is a reversing gate dangerous?
The reversing itself is the safety system working correctly. What is not good is leaving it: each cycle drives the gate into real resistance under power, which wears the operator and the gate, and the property sits unsecured because the gate ends up open every time.
Why did this start suddenly when nothing has changed?
Usually because the change was gradual and the threshold was crossed suddenly. Wear accumulates invisibly for years until the effort finally exceeds the setting, and then it appears overnight. In this region a dry spell moving a post is the most common trigger for a gate that was fine last month.
