Short answer: If an automatic sliding door in Sharjah stays open, will not open, or sweeps shut too hard, start with the sensor, the floor track and the power, in that order. Photograph the sensor and track, then note whether it fails at rush hour. Repair companies near you in Al Majaz, Al Qasimia or Al Heera can diagnose faster with that.
How automatic sliding doors fail in shops, clinics and offices
A sliding door is a simple machine with a smart front end. A sensor above the door sees a person, the controller tells the drive unit to move, a belt pulls the leaves along their track, and a second set of sensors watches for people in the way. When someone types "automatic sliding door repair near me Sharjah" they usually see one of five behaviours: stuck open, stuck closed, slow or noisy, bouncing at the end, or opening for no one. Each points to a different part.
The wider guide to automatic door repair covers all door types. This page stays with sliding glass doors and the districts of Sharjah where we hear about them.
Symptom table: what to check first
| What the door does | Likely cause | Safe check you can do |
|---|---|---|
| Stays open all the time | Sensor sees movement, dirt on lens, or a blocked safety beam | Wipe the sensor lens, clear anything near the door |
| Does not open at all | Mode switch on lock or night, power off, controller fault | Check the mode selector and the power isolator |
| Opens, then closes on people | Safety sensor misaligned or dusty | Look for a bumped sensor and clean it |
| Jerks or judders | Dirty floor track, worn rollers, belt wear | Vacuum the track, do not oil it |
| Grinding or squeaking | Hanger wheels, guide on the floor, glass rubbing | Record a short video with sound |
| Opens by itself | Sensor picks up the fan, a plant or a reflection | Note what moves in front of the sensor |
| Does not close fully | Obstruction, closed limit drift, seal catching | Look for debris at the floor guide |
A longer breakdown of sensor problems is in automatic sliding door sensor problems. If the door will not move or is trapping someone, switch it to manual or open mode and call us before you force it.
The five checks, in order
1. Mode and power
Many "failed" doors are set to lock or one way mode on a selector near the top of the door or on a wall switch. Check it before anything else. Then confirm the supply is on and the unit shows its normal light.
2. Sensor lens and view
Dust, spray from a mop, or a sticker added to the glass can make a sensor see things that are not there. Wipe with a soft dry cloth. Notice whether a new sign, curtain or plant has moved into its view.
3. Floor track and guide
Sand blows into shop entrances in Sharjah all year. A grit filled track is the number one cause of noise and sticking. Vacuum it and note anything bent or broken. Never spray oil in the track, since it turns dust to paste.
4. Glass and seals
Look at the gap between leaves. A leaf that has dropped slightly will rub at the bottom, and a missing brush seal lets in dust. Do not force the leaf.
5. Behaviour pattern
Does it fail only at peak hours, after cleaning, in the afternoon sun, or when the AC cycles? A pattern is a clue worth writing down.

A weekly routine for shop and clinic staff
Most nuisance faults are avoided by a few minutes of care. Give one person the job and keep a note of the date.
- Daily: sweep the entrance, check that nothing leans on the glass, and watch the door complete a full cycle at opening time.
- Weekly: vacuum the floor track and guide, wipe sensor lenses with a dry cloth, and check the mode selector is where it should be.
- Monthly: look at the brush seals, listen for new noises, and confirm the door stops when you step into the closing path.
- After building works or a big clean: check the sensors have not been knocked or splashed, because fitters and cleaners often bump them.
Keep trolleys, boxes and signage away from the sensor view. If you notice the door reacting differently in the afternoon sun, say so, because some sensors are sensitive to strong light through the glass. These small observations are often what separates a quick fix from a repeat visit.
Repair or replace the operator
- Repair when the door is mechanically sound and a sensor, belt, wheel or controller is the fault.
- Replace the drive unit when parts for an old unit are scarce or the gear is worn, but the glass and frame are good.
- Replace the whole door when the frame is bent, the glass is damaged or the opening is changing use.
For glass and door planning see automatic sliding glass doors and the service page for revolving and sliding glass doors.
Safety first for staff and customers
Sliding doors that close on a person are dangerous, particularly for children and people with walking aids. If the door is behaving unpredictably, put it in a safe open mode, place a sign, and arrange a visit. Never bypass or tape a sensor to keep the door open. If you need a refresher on door safety devices, read activation sensors for automatic doors explained.
What to send us for a repair visit
- A photo of the sensor above the door and its label.
- A photo of the drive unit cover, with the cover removed only if safe to do so.
- A short video of the door failing, with sound.
- The mode selector position and any lights shown.
- The building name, floor and access time.
What affects the cost of automatic sliding door repair
We do not quote figures online because a sensor clean, a roller change and a controller replacement are very different jobs. The factors are the type and age of the operator, whether parts are in stock, the glass size and weight, how many leaves, how easy access is, and whether the work must happen outside opening hours. If you have a maintenance contract, a lot of these are caught earlier. See our maintenance plans for how visits are arranged.
Frequently asked questions
Who can repair an automatic sliding door near me in Sharjah?
Choose a company that tests safety sensors after repair, can read the controller and brings common parts. Send photos of the sensor and drive cover, plus a short video, so the first visit is more useful.
Why does my automatic door keep opening by itself?
The sensor may be picking up a fan, a plant, a reflection or moving signage. Dust on the lens or a changed sensitivity setting can also cause it. Note what moves in front of it, and we can adjust or reposition the sensor.
Why will my sliding door not close in a Sharjah shop?
Look for debris in the floor guide, an object in the safety beam, or a seal catching. If the floor is clear and the door still stays open, the safety sensor or controller needs a technician.
Is it safe to use my door in manual mode?
Manual or open mode is a reasonable short term step if the door is moving freely. Use a sign, keep the path clear, and arrange repair. Do not use manual mode on a door that grinds or sticks.
How often should a sliding door be serviced?
Busy doors in shops, clinics and malls benefit from regular visits to clean tracks, test sensors and check belts and rollers. Quieter doors can be less frequent. We recommend a plan based on traffic and dust.
Can you repair glass sliding doors in a clinic without closing it?
Where possible we plan work around clinic hours and keep an alternative entrance open. Tell us the opening times and any hygiene rules, and we will arrange access and cleaning.
What brands of sliding door operators do you repair?
We work on common sliding door operators fitted in the UAE, including Dorma, Geze and Tormax type systems as general trade knowledge. We are not an authorised dealer. Send the label photo and we confirm what is practical.
Can I clean the sensor myself?
Yes, with a soft dry or slightly damp cloth while the door is in a safe mode. Do not spray liquids into the sensor, and do not move the sensor angle. If the problem remains, call for a service.
Is an emergency repair for a stuck automatic door possible?
We take urgent calls for doors that cannot be secured or are blocking an entrance, and list them by safety and security risk. We do not promise a fixed arrival time, because it depends on location and workload.
