ABOUT

Larson screen doors are a popular choice for homeowners seeking a convenient and effective way to keep insects out while allowing fresh air to circulate. However, like any moving part, the closer mechanism on a Larson screen door can eventually become misaligned, leading to a door that slams shut too forcefully, swings open too easily, or fails to close completely. Understanding how to adjust your Larson screen door closer is crucial for maintaining its functionality and extending its lifespan. This guide will walk you through the process, covering various adjustment points and troubleshooting common problems.

Identifying Your Larson Closer Model

Before attempting any adjustments, it's vital to identify the specific model of your Larson screen door closer. Larson offers various models, each with slightly different adjustment mechanisms. The location of the adjustment screws and the type of adjustment (e.g., speed, tension) might vary. Consult your owner's manual – this is the most reliable source of information for your specific model. The manual should clearly illustrate the components of the closer and provide detailed instructions for adjustment. If you no longer have the manual, you can often find a digital version on the Larson website by searching for your door's model number, usually found on a sticker on the door frame or the door itself. Taking photos of the closer before you begin can also be helpful for referencing later.

If you can't find your manual or identify the model, closely examine the closer mechanism. Note the locations of any screws or adjustment knobs. Online resources like YouTube can also be helpful; searching for "Larson screen door closer adjustment" along with your door model (if known) may yield videos demonstrating the process.

Adjusting the Closing Speed

The closing speed is often the most common adjustment homeowners need to make. A closer that slams the door shut too forcefully can be damaging to the door and frame over time. Conversely, a door that closes too slowly might not latch properly, allowing insects to enter. The adjustment for closing speed usually involves a screw located on the closer body itself. This screw is often identified by a symbol indicating speed, or it might be labeled "speed" or "closing speed."

To slow down the closing speed, you typically turn the screw clockwise. Turn it in small increments, testing the door's closing speed after each adjustment. To speed up the closing speed, turn the screw counter-clockwise. Remember, small adjustments are key. Turning the screw too much in either direction can render the closer ineffective. If you find yourself needing to make significant adjustments, it might indicate a problem beyond simple speed adjustment; there could be a problem with the door's alignment or the closer itself.

Adjusting the Latching Strength

The latching strength dictates how firmly the door latches when it closes. A weak latch might allow the door to swing open easily, while an overly strong latch can be difficult to open. This adjustment is often separate from the closing speed adjustment. Look for a screw or adjustment knob that is clearly labeled "latch" or "strength." Sometimes this adjustment is incorporated into the closing speed adjustment, but it may require more trial and error to find the right balance between closing speed and latching strength.

To increase latching strength, turn the adjustment screw (clockwise in most cases) slightly. Test the door to see if it latches securely. If the latch is too strong, making it difficult to open, turn the screw counter-clockwise to reduce the strength. Again, making small, incremental adjustments is vital to avoid over-tightening or loosening the mechanism.

Troubleshooting Common Problems

Even with proper adjustments, you may encounter problems with your Larson screen door closer. If the door still doesn't close properly, consider these troubleshooting steps:

Door Alignment: A misaligned door can interfere with the closer's functionality. Check if the door is plumb (vertical) and square (90 degrees to the frame). Adjust the hinges if necessary to correct any misalignment.Obstructions: Examine the door's path to ensure nothing is obstructing its movement. Remove any debris or obstructions that might be interfering with the closer.Closer Damage: Inspect the closer mechanism for any signs of damage or wear and tear. A broken or damaged closer will require replacement.Weatherstripping: Worn or damaged weatherstripping can affect the door's seal and closing mechanism. Replace the weatherstripping if needed.Spring Tension: Some closers have internal springs that can lose tension over time. In such cases, replacing the entire closer is likely necessary.

When to Call a Professional

If you've tried adjusting the closer and troubleshooting the problem, but the screen door still isn't working correctly, it's time to contact a professional. Attempting extensive repairs without the necessary knowledge could lead to further damage. A professional handyman or door installer can diagnose the problem accurately and perform the necessary repairs or replacements.

Remember to always prioritize safety when working with tools and mechanisms. If you're unsure about any aspect of the adjustment process, it's always better to err on the side of caution and consult a professional.
