Door Closers Stop Closing Automatically – How to Stop a Door Closing Automatically


Door closers are indispensable in commercial environments to ensure doors don’t remain open, jeopardizing security, hygiene, and energy efficiency. Furthermore, they prevent doors from slamming shut and damaging their frame and surrounding walls. Get the Best information about درب برقی.

Adjusting the closing speed enables you to precisely customize how quickly your door closes and latches simply by rotating its valve clockwise or counterclockwise.


“If it ain’t broke, don’t fix it”. Unfortunately, this phrase does not always hold when it comes to automatic doors; their many moving parts can become disoriented over time and cause irreparable harm to both their mechanics and electronics – such as changing opening/closing speeds or sensor adjustments that must be made, as well as safety sensors becoming unresponsive or going into malfunction mode altogether.

Automatic doors typically close on their own due to an imbalanced door that wasn’t designed correctly from the beginning. Although initially intended to open and close at a specific rate, over time, its balance has shifted as your house has settled – which may explain why even doors that never self-closed before now do so unexpectedly. If you suspect yours might be unbalanced, simply take this simple test: remove one hinge pin and tap it with a hammer or screwdriver gently until slightly bent before checking with a 6ft level whether it leans more toward the handle side than the jamb.

If it leans toward the handle, loosening its screws may help; then tap it lightly with a hammer until the strike plate moves closer to the edge of the casing, and tightening them again should fix this issue. Otherwise, over time a safety sensor may become blocked or misalign due to condensation build-up, blocked pathways between sensors or dust accumulation on safety sensor eyes as well as loose wires between sensors or motor heads.


Automatic door closers can be an invaluable convenience and safety feature for building occupants, yet they can sometimes become a nuisance and even pose potential health hazards when malfunctioning or closing too quickly. Luckily, however, most issues relating to automatic door closers can usually be solved using basic troubleshooting techniques.

1. Examine Your Sensor: Sensors are vitally crucial in detecting movement and opening or closing doors, so if they become blocked by debris, garbage cans, signage, or decorations on the door, it could be the cause of your problems. Ensure they are adjusted in accordance with manufacturer instructions if this is indeed the case for your door.

2. Check the Track: It is also essential to regularly clean or inspect the track to keep it in top condition since dirt or damage could compromise its functioning over time. It may require replacement if damage occurs – to do this safely, make sure the door opens when needed or try regularly testing its sensitivity in order to identify if any changes need to be made before proceeding with closing mechanism testing or construction work nearby causing vibrations that lead to doors slamming shut as a result of an issue with its closing mechanism (draughts/fan), vibrations caused by nearby construction work vibrations or simply building settlement, among many factors that may contribute – in order to avoid this from happening you should regularly test its sensitivity in order to identify any adjustments needed or adjustments required before proceeding further with closing mechanism testing or testing that could arise before trying any action taken against potential issues with its closing mechanism so as not to cause this consequence arising.

4. Check for Damaged Parts or Wiring: Lastly, all components must be in top working condition and undamaged. This can include performing tests on the control unit with tools such as an advanced scan tool, multimeter, or test light; this will enable you to ascertain the source of your automatic door’s problem and whether professional repair or replacement services should be needed.

Troubleshooting techniques such as these are an excellent place to begin when your automatic door is having issues; however, should the issue persist or there are signs of an electrical fault, you should contact a trained technician. They can safely identify and resolve the issue more efficiently than you could.


No matter if they are used commercially in a mall, office building, or industrial facility or as residential doors in homes, automatic doors require regular inspections, maintenance, and calibrations to ensure optimal functionality. But occasionally, malfunctions may arise that cause them to shut themselves, slamming shut automatically.

Sensors or motors of doors may be to blame, presenting problems. Luckily, there are various easy solutions available to rectify such issues quickly.

Before beginning repair work on doors, it is recommended that they switch off their power source in order to prevent accidental activation and injuries due to electrical shock. Also crucial for successful repairs is creating an uncluttered and clear workspace – remove obstacles or clutter so you can clearly see what needs to be done on them.

One of the primary causes of automatic doors slamming shut is when their sensors or motors are set too quickly, often as a result of too close pedestrian proximity to sensors or being blocked in any way by obstructions to sensor transmissions. If you suspect your sensors might be responsible, try adjusting them so they detect pedestrians who are farther away or closer from the door opening.

One possible cause of slamming doors is loose hinge pins at the bottom hinge. If your door sags in this area, you can easily fix it by taking out and bending the pin inward with a hammer before reinstalling it with enough force that its internal resistance increases and prevents the free movement of your door in this region.

If your latch is misaligning with its strike plate hole, you can also fix this issue without removing or replacing any parts. A metal file or electric planer may help in making this adjustment; use either tool to widen out the strike plate hole until it can accommodate your latch.


Replacement of the door closer mechanism may help alleviate issues like slamming. The type of replacement technique will depend on your specific situation; options include installing an armature spring or installing a damper to slow down its closing speed.

Option 2 is selecting a door equipped with safety sensors that prevent it from slamming shut. These features, which may include photo eyes or safety-sensing edges that detect when an object blocks its closure and prevent it from closing, are typically found on commercial and industrial doors but they can also be added to residential doors for added protection.

Some door closers use hydraulic systems that store energy before gradually releasing it to avoid slamming, while their construction may include weatherproof and corrosion-resistant materials like aluminum for enhanced longevity and long-term use.

Automatic door closers designed with users in mind are typically customizable through adjustable settings like backcheck, sweep speed, latching speed, and closing force. These settings ensure the device can be fine-tuned to suit different environments, such as windy environments or slower foot traffic, such as nursing homes and hospitals.

An ideal door closer should be quiet and simple to use, making it especially helpful in environments where individuals frequently open doors with limited mobility or dexterity. These door closers can also reduce energy costs by eliminating hands-on closing without impacting hygiene levels as much.

Selecting the ideal door closer to your needs depends on numerous considerations, including its weight, its environment of use, and the level of protection required. In addition, you must purchase from a reputable manufacturer with excellent after-sales support and warranty coverage; reading online reviews or speaking to current users about various products can give invaluable insights into their reliability and performance, helping you make an informed decision with certainty.
