2. Check the screws. Make sure that all of the screws on the door closer are tight. 

3. Lubricate the door closer. Apply a small amount of WD-40 or other lubricant to the moving parts of the door closer. This will help to reduce friction and make the door closer work more smoothly.

Door closers are the best option to close the doors automatically. It helps you avoid 

the door crashes and closes it in slow motion. I also use door closers for my home and office doors. I love them because they are not costly and save your efforts somehow. They all have one thing in common: while you release it, a vacuum is created, which pulls the main connecting arm in and forwards this into a kneeling position. Despite the fact that door closers are normally quite dependable and durable, they generally require professional repair. Following processes will help you with door closer repair.

Ideas on how to repair a door closer:

You have to check if the hydraulic arm works properly or not first. If you have a top-mounted system, it can break, or the interior rod on straight ones may corrode and no longer hold the vacuum. You have to check the air pressure screw if the arm is freely moving. This tension screw may be excessively tight or there may be an absence of grease if the arm is stuck and does not move. Apply some lubricants to make it free and repair the movement of the arm.

If the door closer is not working properly, then there must be some mistake in screw adjustment. You have to adjust the screw in different directions and check the movement continuously. If the door works properly after that, then the problem is solved. 

A little screw in the back of all hydraulic door closer systems allows you to alter the level of receiving or outgoing air pressure. You can adjust that screw and examine the movement. If it works then it’s good. If it doesn’t free the valve movement, then you have to replace the air pressure valve.

If all the above processes don’t work and repair the door closer, then you have to replace it. It can be because of the bad working of the door closer. So you have no choice rather than replacing it with a new door closer.

Now you can do door closer repair on your own.
