A jammed or unresponsive electric gate is frustrating, especially when you are trying to leave for work or return home in bad weather. The good news is that many faults have simple causes that you can safely check yourself.
This guide walks you through the most common electric gate problems and explains the simple troubleshooting steps you can take before calling an engineer.
Safety note: Always switch off the power supply before inspecting any electrical components. If you suspect an electrical fault or are unsure about any aspect of your gate system, contact a qualified gate engineer.
Quick Troubleshooting Checklist For Your Electric Gate
Start with these quick checks before investigating further:
- Try opening the gate using the wall-mounted control rather than the remote.
- Test the manual release key to see whether the gate moves freely by hand.
- Check the control panel for flashing lights, error codes, or warning LEDs.
These simple checks often reveal whether the fault is electrical, mechanical, or related to your remote control.
Identify Your Automated Gate Type
Knowing what type of gate you have makes troubleshooting much easier.
- Sliding gates move horizontally along a track or cantilever system.
- Swing gates open inwards or outwards on hinges.
- Bi-fold gates fold back in sections as they open.
If you are unsure which system you have, take a look at our guides to sliding vs swing gates and cantilever vs tracked sliding gates.
Check The Power Supply First
Loss of power is one of the most common causes of electric gate failure.
Inspect The Consumer Unit
Check your property’s fuse box for any tripped circuit breakers or blown fuses. Reset any tripped breakers and test the gate again.
Check Backup Batteries
Many automated gates include battery backup systems to maintain operation during a power cut. If the batteries are flat or failing, the gate may stop working correctly.
Look For Visible Damage
Inspect visible wiring and connections for signs of corrosion, loose terminals, or damage caused by water ingress.
If the system still has no power, professional assistance is recommended.
Gate Motor Problems
The gate motor performs most of the hard work, so motor faults are common as systems age.
Listen For Unusual Sounds
Try operating the gate and listen carefully:
- Humming without movement may indicate a seized motor or failed capacitor.
- Clicking noises can indicate relay or control issues.
- No sound at all may suggest a power or control fault.
Check For Overheating
If the motor feels unusually hot or produces a burning smell, switch the system off immediately and contact a professional engineer.
Many homeowners ask whether electric gates are worth the investment. Regular maintenance is essential to protect that investment and maximise lifespan.
Control Panel And Electronics Issues
The control panel acts as the brain of your automated gate system.
Check Error Codes
Many control panels display diagnostic LEDs or fault codes. Refer to your manufacturer’s manual to interpret these codes.
Reset The Controller
Occasionally, a simple system reset can restore normal operation. Always follow the manufacturer’s instructions when resetting the controller.
Inspect Internal Fuses
Some control panels contain internal fuses which may need replacing if they have blown.
If problems persist after a reset, the control board itself may require specialist repair.
Remote Control Problems
If the wall-mounted control works but the remote does not, the issue is usually straightforward.
- Replace the remote batteries.
- Move closer to the gate and test again.
- Reprogram or re-pair the remote with the receiver.
- Check for possible signal interference from nearby devices.
If the remote only works at very short distances, the receiver or aerial may require inspection.
Safety Sensors And Photocells
Safety devices are designed to stop accidents, but they can also prevent your gate from operating if they become dirty or misaligned.
Clean The Sensors
Dust, cobwebs, insects, and dirt can block photocells. Carefully clean the lenses and remove any obstructions.
Check Sensor Alignment
Misaligned photocells often cause gates to stop, reverse unexpectedly, or fail to close completely.
Inspect Safety Edges
Damaged safety edges may trigger the system to stop operating as a precaution.
Mechanical Problems With Sliding And Swing Gates
Sliding Gate Problems
For sliding gates, debris in the track is one of the most common issues.
- Clear leaves, stones, and dirt from the track.
- Inspect rollers for wear.
- Check for damaged track sections.
Swing Gate Problems
For swing gates, inspect:
- Hinges for wear or movement.
- Loose brackets and fixings.
- Signs of gate sagging or misalignment.
Lubricating moving parts regularly can prevent many common faults.
What To Do During A Power Cut
Every automated gate should include a manual release mechanism.
Locate the release key or lever, usually found on the motor housing. Follow your manufacturer’s instructions to disengage the motor safely and move the gate manually.
Once power has been restored, remember to re-engage the motor before returning the system to automatic operation.
Why Does My Gate Keep Stopping Or Reversing?
If your gate repeatedly stops or reverses unexpectedly, possible causes include:
- Dirty or misaligned safety sensors.
- Obstructions in the gate path.
- Excessive resistance caused by worn rollers or hinges.
- Incorrect sensitivity settings within the controller.
Persistent reversing should always be investigated, as it may indicate an important safety issue.
Preventative Maintenance For Electric Gates
Routine maintenance prevents many common failures.
- Monthly: Clean tracks, rollers, and photocells.
- Quarterly: Carry out a visual inspection of the entire gate system.
- Twice yearly: Lubricate hinges, rollers, and moving components.
- Annually: Arrange professional servicing and safety checks.

When Should You Call A Professional?
Contact a qualified engineer if:
- The motor overheats or emits a burning smell.
- You have persistent electrical faults.
- The control board appears damaged.
- The gate has suffered impact damage.
- The gate remains inoperable after completing these checks.
Frequently Asked Questions
How do you fix an electric gate that won’t open?
Start by checking the power supply, remote batteries, sensors, and any visible obstructions. If the problem persists, contact a professional engineer.
What are the most common electric gate problems?
The most common faults include power failures, flat remote batteries, blocked tracks, dirty photocells, worn motors, and damaged safety devices.
What is the lifespan of an electric gate?
With regular servicing, quality electric gates can last 15 to 20 years or longer. Motors and automation equipment may require replacement sooner depending on usage.
Can I manually open an electric gate?
Yes. All automated gates should include a manual release mechanism for use during power failures or emergencies.
