Gate Not Working After a Storm

Storms damage gates in three distinct ways, and they need different responses. The one that matters most is the least visible: a gate that still moves but has lost its safety devices is more dangerous than one that has stopped.

How we approach gate not working after a storm

  • Safety devices are verified before we hand a storm-damaged gate back
  • Surge damage is traced through transformer, board and detector rather than guessed at
  • We document damage properly if you are making an insurance claim

Safety risk

Storm-damaged gates can have intact-looking operators and damaged safety devices, which is the dangerous combination. Do not cycle it repeatedly to see if it recovers.

Check these first — before you call anyone

Some causes of gate not working after a storm you can resolve yourself in minutes. We would rather you found one than paid us to.

  1. 1

    Check the GFCI and breaker first

    The most common post-storm fault is also the cheapest. Reset the GFCI near the operator and check the panel. A large share of gates are working again at this point.

  2. 2

    Inspect the safety sensors before doing anything else

    Look at both photo-eye housings for knocks, water inside the lens, or damaged cabling, and check their indicator LEDs. If a sensor is damaged, do not return the gate to normal operation until it is repaired — that is the protection that stops it closing on something.

  3. 3

    Walk the gate by hand

    With the operator released, move the gate through its full travel. Binding, scraping or new noise means physical damage. Look for debris in the track and for a leaf that no longer sits square.

  4. 4

    Photograph everything before it is touched

    If you may claim on insurance, photograph the damage, the debris and the position of the gate before anything is moved or repaired. It is much harder to evidence afterwards, and it costs a minute now.

What not to do

  • Do not repeatedly cycle a storm-damaged gate to see whether it recovers. If a safety device is damaged, each cycle is a gate closing without protection.
  • Do not reset a GFCI more than once if it keeps tripping — water has reached something.
  • Do not touch a gate that is near a downed power line or a damaged supply. Call the utility first.
  • Do not straighten bent track or lever a moved post by hand; both are structural and both get worse when improvised.

Checked all that and it is still gate not working after a storm?

Tell us what you found — it shortens the visit.

What is actually happening

Three mechanisms, three different repairs

The first is electrical surge. Lightning does not need to strike the gate — a strike on the network induces a spike that travels the supply, and the transformer, control board and loop detector are the usual casualties. This can leave a gate completely dead or working with one function missing.

The second is water. Driven rain finds its way into enclosures whose seals have aged, into photo-eye housings, and into loop splices in the driveway. These faults often appear a day or two later rather than immediately, and they may come and go as things dry.

The third is physical. Wind moves gate leaves hard against their stops, debris hits them, and a large leaf acts as a sail. That bends track, knocks photo-eyes out of alignment, strains hinges and occasionally shifts a post. Physical damage is the one that most often leaves a gate that still runs but is no longer safe.

Why a gate that still works may be the more dangerous outcome

A dead gate announces itself. A storm-damaged gate that still opens and closes may have a photo-eye knocked out of alignment, an edge sensor with a severed cable, or a loop detector reading permanently — and those faults remove the protection that stops the gate closing on a vehicle or a person without preventing it from closing.

That is why the checks on this page are about the safety devices rather than about getting the gate moving again. A gate that has been through a storm should have its entrapment protection verified before it goes back into normal service, and that is not something that can be confirmed by watching it complete one cycle.

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.

Surge damage to the transformer or control board

most common
How to tell
The gate is completely dead, or one function has vanished while others work. Supply to the operator tests live. There may be a burnt smell or visible scorching on the board.
The fix
Transformer or board replacement, and fitting surge protection if none exists. Without protection, the replacement board is exposed to the next storm exactly as the first one was.

Tripped GFCI from moisture

most commonYou can often fix this
How to tell
Total silence from the operator, and the GFCI near the post has tripped. This is the single most common reason a gate is dead the morning after a storm, and it is free to fix.
The fix
Reset it. If it holds, nothing further is needed. If it trips again, water has reached something and that needs tracing rather than resetting.

Photo-eyes knocked out of alignment by wind or debris

commonYou can often fix this
How to tell
The gate will not close, or closes and reverses. Look at the sensor housings — a knock of a few degrees is enough and is often not visually obvious. Check the indicator LEDs.
The fix
Realignment, or replacement where the housing or cable is damaged. This is also the check most often skipped after a storm, which is why it is on this page twice.

Water in the loop splice or detector

common
How to tell
The gate opens by itself, or will not close, starting during or shortly after heavy rain. The loop detector LED shows detection with an empty driveway.
The fix
Drying and resealing the splice, or replacing a detector module damaged by surge.

Physical damage — bent track, strained hinge, moved post

common
How to tell
Release the operator and move the gate by hand. Binding, scraping or a changed gap at the hinge side means the gate itself took the damage. Look for debris strike marks and for a leaf that no longer sits square in its opening.
The fix
Mechanical repair — straightening or replacing track, resetting hinges, re-squaring the leaf, addressing the post. The operator should not be re-commissioned until the gate is square again.

Lost travel limits after the power interruption

less common
How to tell
Lights and response are normal but the gate will not complete a cycle, or moves a short distance and stops. Some operators discard learned positions after an interruption.
The fix
Re-learning the travel. A short visit and no parts, provided the gate itself is undamaged.

Repair, or replace?

Most storm damage is repairable and a good deal of it is inexpensive — a reset, a realignment, a dried splice. Surge damage to boards is the costly end, and it is the one worth preventing: if a storm has taken a board out once, surge protection is cheaper than the next board.

Usually a repair

  • GFCI and breaker resets
  • Photo-eye realignment and replacement
  • Loop splices and detector modules
  • Transformers, fuses and boards where still supported
  • Track, hinge and alignment damage

Sometimes a replacement

  • A board on a discontinued operator with no supported replacement
  • An operator that took a direct strike, where multiple subsystems are damaged at once

Why this happens in Dallas–Fort Worth

This metroplex earns its storm reputation

North Texas sits in one of the most active severe-weather corridors in the country, with a spring and an autumn season of straight-line winds, large hail and heavy lightning. Gate equipment is outdoors, tall, metallic and at the end of a long buried run, which is close to the worst combination available.

The wind is the underrated part. A solid gate leaf is a sail, and the straight-line winds that come off these storm lines routinely exceed what a gate’s stops and hinges were designed to absorb. Hail damages photo-eye lenses and enclosure seals. A gate that survived the storm intact still deserves a look at its sensors, because the damage that matters most is the kind that leaves it working.

Gate not working after a storm — common questions

Frequently Asked Questions

My gate died the night of a storm. Is it the lightning?

Sometimes, but check the GFCI first — moisture tripping the outlet near the post is the most common post-storm cause and it is free to fix. If the GFCI is fine and the supply is live but the operator is dead, then surge damage to the transformer or board becomes the likely answer.

The gate still works after the storm. Do I need it checked?

Yes, and specifically the safety devices. Wind and debris knock photo-eyes out of alignment and damage sensor cables without stopping the gate, which leaves a gate that closes normally but no longer detects an obstruction. That is the one storm outcome that is genuinely dangerous.

Will my insurance cover storm damage to a gate?

That is between you and your insurer, but photograph everything before anything is moved or repaired — the damage, the debris, and the gate’s position. We can provide a written description of the fault and the repair for a claim. Evidence is much harder to produce after the repair.

How do I stop this happening again?

Surge protection is the single most effective step if a board or transformer has been lost, and it costs a fraction of the part it protects. Beyond that, keeping enclosure seals in good condition and having sensor cabling properly strain-relieved deals with the water and flex damage that follow storms.

It worked for a day after the storm and then failed. Why the delay?

Water. Moisture that got into an enclosure, a photo-eye housing or a loop splice during the storm takes time to reach a terminal and start causing trouble, and the fault may come and go as things dry out. Delayed failures after rain are one of the more reliable signatures we see.
