When a screen door works correctly, it can glide open and close easily, barely making a sound. However, when it’s not working, it can be a big source of frustration for homeowners. Issues commonly resulting from a faulty pneumatic door closer include a door slamming behind you or sticking halfway open.
If you’re dealing with these or similar problems and don’t know what to do, you’re in the right place. Learn how to adjust a pneumatic door closer and get your screen door working like it’s brand new.
What Is a Pneumatic Door Closer?
If you have a storm door, you’ve probably noticed the long tube attached to the inside of the door. This tube, which keeps the door from slamming shut, is called a pneumatic door closer.
The device uses compressed air to control the speed and force of the door’s closing action. A pneumatic door closer also comes with a small washer to hold the door open for periods of time if you’re moving things in and out of the doorway.
How Do Pneumatic Door Closers Work?
Pneumatic door closers consist of a cylinder filled with air and a piston. When you open the door, the piston compresses the air inside the cylinder. When you shut the door, the compressed air pushes the piston back out.
This compressed air determines the speed of the door’s closing action. The spring and air pressure balance guarantees the door doesn’t close too quickly or slowly.
Common Issues With Pneumatic Door Closers
Several problems can occur with pneumatic door closers over time:
- The door closes too quickly or slams shut.
- The door doesn’t close completely.
- The door closes too slowly.
- The closer makes unusual noises while in operation.
You can resolve most of these issues by simply adjusting the door closer.
Tools Needed for Adjusting a Pneumatic Door Closer
To adjust your door closer, you’ll need a few everyday tools:
- A screwdriver (flathead or Phillips-head)
- Pliers (optional)
- Lubricating oil (optional)
These tools will make the adjustment process smoother and more efficient.
Adjusting the Bracket
If the door isn’t closing completely, adjusting the bracket that attaches the closer to the door may solve the problem. Here’s how to do it:
- Open the door and slide out the stop to hold the cylinder open.
- Locate the screws that attach the bracket to the door.
- Loosen these screws by using the appropriate screwdriver.
- Move the bracket further out toward the door handle.
- Tighten the screws to secure the bracket in its new position.
Alternatively, you can adjust the position of the cylinder within the bracket:
- Remove the pin that secures the cylinder to the bracket.
- Move the cylinder to a hole further away from the door.
- Reinsert the pin to secure the cylinder in its new position.
Adjusting the bracket guarantees the door closes snugly against the frame without leaving any gaps.
Adjusting the Pneumatic Cylinder
If the door slams shut too quickly or closes too slowly, adjusting the pneumatic cylinder can help regulate the closing speed. Here’s how to make this adjustment:
- Locate the adjustment screw at the end of the pneumatic cylinder.
- To slow down the closing speed, turn the screw clockwise.
- To speed up the closing action, turn the screw counterclockwise.
- Make small adjustments and test the door after each turn until you achieve the desired closing speed.
A little adjustment goes a long way. Make small turns and test the door frequently to avoid over-adjusting. This step is worth taking since a well-calibrated door closer can prolong the door’s life and make it operate more quietly.
When To Replace a Pneumatic Door Closer
While many issues can be resolved through adjustment, you’ll eventually have to replace your door closer. It’s a good idea to replace your pneumatic door closer if it looks damaged, your adjustments don’t work, or the door closer is over 7 years old.
When purchasing a replacement, take the old door closer to the home improvement store to be certain the new one will fit the existing hardware on the door. This will save you a lot of trouble later on.
Door Closer Replacement Costs
According to Angi, the price of a new pneumatic door closer and all replacement materials typically ranges from $25 to $50. Some pneumatic door closers at Home Depot are available for $15 or less. As DIY home projects go, this one is on the cheaper side.
