Automatic doors are one of those things you hardly notice when they’re working as they should. You walk up, they slide open, and you get on with your day. But when one starts sticking, opening for no reason, it can hold up customers, create a security issue or even become a safety risk.
Here’s a straightforward look at common automatic door repair problems, what you can safely check yourself, and when it’s best to get a local engineer in.
Before assuming the whole system has given up, have a quick look at the simple stuff. Sometimes it’s just dirt in the track, something blocking the sensor or a power issue.
Automatic doors have a few moving parts that all need to work together—sensors, rollers, tracks, motors and control units. If one small thing is out of place, the door can start acting up.
Check whether there is anything sitting near the doorway or sensor area. Signs, bins, stock displays, mats or even a bit of rubbish can cause problems. Also check that the power is on and no emergency stop button has been pressed by accident.
If you are not sure what you are looking at, don’t start taking covers off or poking around with wires. It is better to leave the electrical side alone.
If the door’s not opening when you walk up to it, the sensor’s usually the first thing to have a look at. Give it a quick wipe with a soft, dry cloth—dust, cobwebs and general muck can stop it picking up movement properly. While you’re at it, make sure there’s nowt sat in front of it blocking the sensor.
If it’s still playing up or only works now and then, there could be an issue with the sensor itself, the wiring or the control unit. At that point, it’s best to get someone in to take a proper look.
At that point, it’s best not to mess about with it—get a professional in for automatic door repairs.
If the door keeps opening when there’s no one about, it can be a right nuisance—especially when you’re trying to keep the place warm and secure.
It might be picking up movement outside, reflections off the glass, cars going past or people walking by. Sometimes it’s something simple, like a sign, plant or display placed too close to the sensor.
Try moving anything near the entrance and see if it settles down. If it keeps happening, book automatic door servicing so a technician can check the sensor settings and alignment properly. Leaving it to open and close all day can put extra wear on the motor.
If your automatic door’s dragging, stopping halfway or scraping along the track, summat’s clearly not right. It could be muck building up, worn rollers, a loose belt or a part that’s shifted out of place.
Have a quick look for leaves, grit or any bits of rubbish sat in the visible track. If there’s a safe way to switch the door off, do that before you clean around it.
Don’t go chucking WD-40, oil or any old lube into the track or motor. It might seem like a quick fix, but it’ll only drag more muck in and make it worse down the line.
If it’s still sticking after you’ve given it a clean, best get someone in to have a proper look at it. A small issue can soon turn into a bigger, more expensive automatic door repair if it’s left too long.
A working automatic door should run nice and smoothly. A quiet hum’s usually nothing to worry about, but if it’s grinding, scraping, squeaking or clicking properly loud, something needs checking.
Could be worn rollers, a damaged track, loose bits or an issue with the motor. Have a quick look for anything obvious, like a loose panel, bent rail or damage around the frame.
If it’s making a proper grinding noise, smells burnt or starts moving all wonky, stop using it if you can and get someone out to look at it. Keeping a dodgy door running can make the damage worse and put people at risk.
They won’t fix every problem, but they can help rule out the simple stuff first:
Some issues need a proper fix straight away. If the door is unreliable, unsafe or stuck, it is time to call a local company for automatic door repair.
Get help if:
It is especially important to act quickly if the door is at a busy shop, office, care home, school or shared building. You do not want people being forced to use an unsafe entrance.
If you’re giving the house a bit of a spruce-up, you may as well sort the doors and windows while you’re at it. Solid shutters in Derby are a proper good shout for a bit more privacy, keeping the warmth in and making the bedrooms, living room or front windows look dead smart.
Bay windows can be a right faff with standard blinds—they leave little gaps or just never sit quite right. Bay window shutters are made to fit the shape and angles of the window, so they look neat and like they’ve always been there.
You still get the privacy you need without blocking out all the daylight, which is always a bonus.

Sometimes it’s just a dirty sensor or a bit of rubbish in the track. But if the door’s acting strange, making a racket or causing a safety issue, don’t keep messing about with it—book professional automatic door repairs and get it fixed properly.
