Common Automatic Gate Problems and How to Fix Them

Automatic gates are a great addition to any property. They offer security, ease of access, and a good-looking entrance. But like any system with moving parts and electronics, they can go wrong. Whether your gate refuses to open, keeps getting stuck, or beeps for no clear reason, it can be a real hassle, especially if you're trying to leave for work or welcome visitors.

In this blog, we’ll look at the most common problems that automatic gate owners face, explain what causes them, and show you simple steps to fix or prevent them. We’ll also cover when it’s best to leave it to the professionals.

Gate won’t open or close at all

This is probably the most frustrating issue. You press the remote, but nothing happens. The gate sits still, and you’re stuck. Here are the most common causes.

Power failure

Most automatic gates are powered by mains electricity. If there’s a power cut, tripped fuse, or faulty wiring, your system won’t work. Check your fuse board and the power supply to the control unit. If you have solar power or a battery backup, make sure those systems are working correctly.

Faulty remote control

Try a spare remote if you have one. If that works, the problem is likely the battery in the first remote. Replacing the battery usually solves it. Also, check your distance. Some remotes lose signal strength over time. Standing closer to the gate may help.

Manual release is engaged

All automatic gates have a manual release function. It’s usually used during power cuts or emergencies. If someone has recently used this and not re-engaged the system properly, the gate will stay inactive. Make sure the gate is back in automatic mode.

Obstruction in the path

Swing gates and sliding gates can be stopped by something as small as a stone or pile of wet leaves. Carefully inspect the area around the gate and the motor track. Clear away anything that could be blocking movement.

Gate opens or closes halfway then stops

This is another common problem. The gate starts moving but either stops before it's fully open or reverses direction.

Obstruction or debris

Start with the basics. Check for physical objects in the path, especially with sliding gates. Even a small stick or loose stone can activate the safety sensor and stop the gate. Clear the track or area and try again.

Faulty safety sensors

Most modern gates have sensors to detect objects or people. If these sensors are dirty, out of alignment, or faulty, they may falsely detect something and stop the gate. Clean them gently and make sure nothing is blocking their view.

Motor overload

If the gate motor is struggling, it may shut off to protect itself. This can happen if the gate is stiff, if hinges or rollers are rusty, or if it hasn’t been serviced in a while. A technician may need to inspect the motor or adjust the system.

Remote works sometimes but not always

If the remote only works on and off, it may not be a full failure, but it’s still inconvenient.

Weak battery

A low battery can cause signal problems. Replace it first and test again.

Signal interference

Wi-Fi routers, electric fences, or other nearby gates can interfere with your gate’s receiver. Try standing closer or changing the remote frequency if your system allows it.

Faulty receiver

If all remotes are affected, and there’s no interference nearby, the gate’s receiver could be faulty. This is usually a job for a qualified installer.

The gate is making strange noises

Unusual sounds often mean something is wearing out or needs maintenance.

Grinding or screeching

These noises usually come from hinges, rollers, or tracks. Dirt and rust can build up over time. Lubricate the moving parts with a gate-safe product, and clean out any grit or leaves.

Beeping sounds

Most gate control systems include beepers to signal faults or low battery. A constant beep could be a power issue, while a repeated beep might signal a sensor fault or an incomplete cycle. Check your gate manual for specific codes or light signals.

Gate is moving slowly

Automatic gates are designed to move at a steady speed. If yours feels slower than usual, it may be down to the following:

Cold weather

In winter, motors can be slower to start. Hydraulic systems in particular don’t like the cold. If your gate works fine later in the day, this may be the cause.

Low battery or poor power supply

Weak power can affect the speed and performance of your system. If you're using solar power, check that your battery is holding charge. If the gate is mains-powered, the supply may need to be checked by an electrician.

Worn motor or components

Like any machine, motors wear out over time. If your gate is several years old, the motor may be showing signs of age. Have it serviced or inspected by a professional.

The gate opens randomly

A gate that opens on its own can be both worrying and dangerous.

Remote interference

If another nearby device is on the same frequency, it may accidentally trigger your gate. This is rare but possible, especially in built-up areas.

Faulty circuit board

A damaged or waterlogged circuit board inside the gate control unit can send out incorrect signals. If this is the issue, the control panel will likely need to be replaced.

Preventing problems with regular maintenance

Many gate issues can be avoided with simple maintenance. Just like your car, your gate needs attention now and then.

• Keep tracks and hinges clean

• Lubricate moving parts every few months

• Clear leaves and dirt after bad weather

• Check batteries in remotes twice a year

• Book a service check every 12 to 18 months

Your installer may offer a maintenance plan. If so, it’s worth signing up, especially if your gate is used daily.

When to call a professional

Some issues are easy to fix. But if you’ve checked the power, cleaned the sensors, changed batteries, and your gate still won’t work, it’s time to call a technician. Electrical faults, motor failures, and control board problems should always be handled by a trained expert.

Never try to force the gate open or take apart the motor unless you’re qualified. This can cause more damage or even injury.

Final thoughts

Automatic gates are reliable most of the time. But when problems arise, knowing what to check first can save time and stress. Always start with the basics. Power, remotes, and obstructions cause more issues than you might expect. For anything more complex, don’t hesitate to get in touch with a gate engineer.

With the right care and regular checks, your automatic gate can keep your property secure and make life that bit easier every day.
