All you might need is a pair of screwdrivers and you are good to go on a quick DIY task.

Door Closer Problems

There can be undue pressure or sturdiness in a door closed if the installation was not done properly. If you are not a professional and take up this task on your own, there can be potential flaws in the placement. Then, depending on the construction of the door, for example, if it is made of glass, a problem with the door closer can translate to a bigger problem if the entire door might need replacement.

  • Withstand heavy winds is not the task for a light-duty door closer. It cannot just damage your door closer, or even break it; it can break the door itself. The tiny arm supporting the tension and pressure can snap apart, resulting in the door to slam hard and even break around the frames. Therefore, applying a door closer should start with the intended application.
  • Light duty door closers are more appropriate for an indoor setting while areas where you have frequent hurricanes and gale-force winds, you are in trouble. For the main doors that directly face the winds, using a heavy-duty door close, in some cases more than one is a necessity. While in an office inside a building, in front of your personal cabin, light-duty door closers are more than sufficient because they are just to close the door behind a person.

Misalignment

  • Misalignment is another big concern for door closers. If the installation was improper and the placement or the type of door closer is unsuitable for the weight and torque of the door, the door closer can cause misalignment.
  • It can result in warped doors, shattered glass, slamming of doors, and frame damage. If the door closer was installed right when installing the door, the problems can grow with time, and within a few months can affect the opening and closing of the door itself.
  • Some low and cheap quality door closers do not have the proper functionality and parts. For example, you would want your door closer to at least have a dead stop.
  • The dead stops are small rubber parts that keep the door from opening any further, like small bumpers. The rubber helps to soften the blow against the arm of the closer as well. This allows it to increase the tension and avoid overextension of the closure.

Use an Open-Ended Wrench

  • Using an open-ended wrench, you can turn the spindle of the door closer to the hold-open position. One must make sure that the turns are in the right direction, some have clockwise and some might have anticlockwise. If the door closer has no hold-open feature, turning the spindle with the open wrench until it gets to 90 degrees is a suitable idea.
  • Then, the closing-speed adjustment spring or valve is visible. In some dor closers, the screws are set aside for easy adjustments. Turning around a complete turn can stiffen the springs by one unit. You can always check and see if you are happy. In such cases, you don’t have to remove the closer to make adjustments, and this saves time and effort.

Sweep

  • The first adjustment is the Sweep. This controls the speed. This is usually available on one side of the door closer. The other one is ‘Open’, which is on the other side of the closer. They can both rotate clockwise or anticlockwise to make adjustments to speed and opening torque.
  • For example, if the closer is tight when opening, which is not advisable and slams close very quickly, again undesirable, the ‘Sweep’ and ‘Open’ must go clockwise in both cases. Using the Allen key turn the right side about a quarter turn, and check where it gets you. Then, turn the other side with the Allen key and see what change it does.
  • By simply changing the turns, that is tightening the screws, and checking by opening and closing the door, you can set them, or reset them to the right amount of torque and speed.
