A gate that does nothing at all is usually one of four things, and three of them you can identify yourself in ten minutes. This page walks the same order a technician works in, so you know what you are dealing with before you pay anyone to look.
Also described as “automatic gate not working”, “electric gate not working”, “gate opener not working”, “gate motor not working”.

Access blocked
A gate that is dead in the closed position locks you in or out; dead in the open position leaves the property unsecured. Either way it is worth the ten minutes of checks below before anyone is called out.
Check these first — before you call anyone
Some causes of automatic gate not working at all you can resolve yourself in minutes. We would rather you found one than paid us to.
1
Check the obvious power sources
Find the GFCI outlet feeding the operator — often in a weatherproof box on the post, sometimes in the garage — and press reset. Check the breaker. On a solar unit, look for a low-battery indicator on the board. This one step resolves a meaningful share of dead-gate calls at no cost.
2
Release the operator and push the gate by hand
Every operator has a manual release, usually a key or lever on the housing. With it released the gate should move freely with one hand. If it does not, the fault is mechanical and you can stop looking at electrical causes entirely.
3
Listen carefully when you trigger it
Total silence, a hum, or a single click are three different diagnoses. Stand at the operator and have someone press the remote. What you hear narrows the fault more than anything else you can do without tools.
4
Look at the board’s indicator lights
Most modern boards show power and fault status, and many flash a code. Photograph the board and the flashing pattern before calling — it frequently identifies the fault before a technician arrives, which shortens the visit.
What not to do
Do not keep resetting a breaker that trips again immediately. It is doing its job; something is faulting to earth.
Do not force a gate that is bound on its track. You will bend the track, damage the rollers, or pull a post — all more expensive than what stopped it.
Do not open a control board enclosure in the rain, or with the supply live, unless you are qualified to.
Do not bypass or disconnect a safety sensor to make the gate move. That is the protection that stops it closing on a car or a child.
Checked all that and it is still automatic gate not working at all?
A gate operator is two systems, and only one of them is electrical
Every automatic gate is a gate plus an operator. The gate is the leaf, the hinges or rollers, the posts and the track — pure mechanics that would still move if you disconnected every wire on the property. The operator is the motor, gearbox, control board and safety devices that move it for you.
Almost every wasted call-out on a dead gate comes from confusing the two. An operator straining against a gate that has seized on its track will trip out, overheat, or click and stop — behaviour identical to a failed capacitor. The difference costs a few hundred dollars, and it takes thirty seconds to tell them apart: release the operator and push the gate by hand. If it fights you, the fault is mechanical and no electrical part will fix it.
Dead, and dead-sounding, are different diagnoses
Silence means the board is not receiving power or has failed outright: no hum, no click, no LED, nothing at the keypad. That points upstream — the breaker, the GFCI outlet, the transformer, the battery on a solar unit, or the board itself.
Noise without movement means the board is alive and trying. A hum is the motor energised but unable to turn, which is a seized gearbox, a failed start capacitor, or mechanical binding. A single click and then silence is usually a relay on the board or a capacitor that can no longer start the motor. The distinction matters because it tells you which half of the system to open first.
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.
No incoming power — tripped breaker, GFCI, or a switched-off disconnect
most commonYou can often fix this
How to tell
Nothing at all: no LED on the control board, no beep, no response from keypad or remote. Check the GFCI outlet the operator is plugged into — they are often in a weather box on the post or inside the garage and they trip in storms.
The fix
Reset the GFCI or breaker. If it trips again immediately, stop: something downstream is faulting to earth and it needs a technician rather than another reset.
Dead or exhausted battery on a solar or battery-backed operator
most common
How to tell
Common on acreage installations. The gate worked in the afternoon and is dead by morning, or it has been getting progressively slower for weeks. Many boards show a low-voltage LED or beep a pattern.
The fix
Battery replacement, sized for the number of cycles you actually run. If the panel is shaded by a tree that has grown since installation, that gets fixed at the same time or the new battery follows the old one.
Failed start capacitor
common
How to tell
The classic signature is a hum with no movement, or a gate that starts only if you give it a push. On AC operators the capacitor is a cylinder inside the housing, and a failed one is often visibly swollen or leaking.
The fix
Replacement is a small part and a short visit. A capacitor must be tested under load — testing it cold reads fine on units that fail the moment they are asked to start a motor.
Mechanical binding — the gate itself has seized
common
How to tell
Release the operator per the manufacturer’s instructions and push the gate by hand. It should move smoothly with one hand. If it drags, catches at a point, or will not budge, the operator is innocent.
The fix
Depends what is binding: a fouled or bent track, a failed roller, a dropped hinge, or a post that has moved. All are mechanical repairs, and all of them destroy operators if they are left and the operator is asked to fight them.
Failed control board
common
How to tell
Power is confirmed at the board but nothing responds, or the board’s LEDs are dark or showing a fault code. On older operators this is more likely simply because the board has been outdoors through fifteen Texas summers.
The fix
Board replacement where one is still made for the model. On discontinued operators this is the point where we tell you honestly whether the unit has a future.
Burnt-out motor or seized gearbox
less common
How to tell
Usually the end of a story rather than a surprise: the gate has been slow, noisy or struggling for months, and there may be a burnt smell at the housing. Power reaches the motor and the motor does nothing.
The fix
Motor or gearbox replacement, and at this point the economics of a new operator deserve an honest comparison — particularly if the unit is out of production.
Transformer failure
less common
How to tell
The operator is completely dead but the supply to it tests live. Common after a nearby lightning strike or a supply surge.
The fix
Transformer replacement. Worth asking whether surge protection is fitted, because an unprotected board is usually the next thing to go.
Repair, or replace?
A completely dead gate sounds like the worst outcome and usually is not. The two most common causes — no incoming power and a flat battery — are the cheapest on the list, and a capacitor is a small part. The genuinely expensive answers, a failed motor or an obsolete board, normally announce themselves with months of warning noise first.
Usually a repair
Power supply faults, tripped GFCIs and failed transformers
Batteries and solar charging faults
Capacitors, relays and limit switches
Control boards, where the model is still supported
Mechanical binding — track, rollers, hinges and posts
Sometimes a replacement
A burnt-out motor on an operator already past its expected life
A failed board on a discontinued operator with no supported replacement
An operator that was under-specified for the gate it moves and has failed repeatedly for the same reason
Why this happens in Dallas–Fort Worth
Heat, storms and clay — the three things that kill gates here
Dallas–Fort Worth runs long stretches above 100°F, and a gate operator is a sealed box in full sun. Heat shortens the life of capacitors and batteries specifically, which is why those two dominate the summer call sheet rather than being spread evenly across the year.
Storm season does the other half. Surges take out boards and transformers, and a GFCI tripped by a storm is the single most common reason a gate is dead the morning after one. Then there is the Blackland clay much of the metroplex sits on, which swells and shrinks by season and slowly moves gate posts — producing the mechanical binding that makes a healthy operator look broken.
Automatic gate not working at all — common questions
Frequently Asked Questions
My gate is completely dead. Is it going to need replacing?
Usually not. The most common causes of a totally dead gate are a tripped GFCI, a flat battery and a failed capacitor — all inexpensive. A dead gate is not a worse sign than a gate that half-works; if anything it is often simpler, because a single point of failure is easier to find than an intermittent one.
How can I tell whether it is the gate or the opener?
Release the operator with its manual release and push the gate by hand. A healthy gate moves smoothly with one hand. If it drags or catches, the problem is mechanical — the track, rollers, hinges or a post — and no electrical part will fix it. That single test saves more wasted money than anything else on this page.
The gate worked yesterday and is dead today. What changed?
Look for what happened in between. A storm is the most common answer in this region: a surge takes out a board or a transformer, or simply trips the GFCI. On solar operators a cold night after a cloudy day will finish a battery that was already weak. Both are the first things we check on a gate that failed overnight.
Can you fix an old operator or do I have to buy a new one?
Often it can be repaired, and we will tell you plainly when it cannot. The mechanical parts of an installation — posts, hinges, track — normally outlast the electronics by decades, so even when an operator has to be replaced the rest of the installation is usually reusable, which puts the cost far below a full replacement.
Is it safe to leave the gate open until someone can come out?
It is safe, but the property is not secured, so tell us if that is the situation and we will treat it as urgent. What is not safe is wiring it to stay closed with the safety devices disconnected, or propping a heavy leaf in a position its hinges were not designed to hold.
