ABOUT

Larson storm doors offer a convenient and practical way to enjoy the fresh air while keeping out the elements. However, a malfunctioning door closer can quickly turn this convenience into a frustration. A poorly adjusted closer might slam shut aggressively, fail to close completely, or even remain stubbornly open. This can lead to drafts, security concerns, and ultimately, damage to your door and frame. This guide will walk you through the process of adjusting your Larson storm door closer, equipping you with the knowledge to restore smooth, reliable operation to your door. Understanding the different adjustment points and how they affect the door's performance is key to success. Before you begin, ensure you have the right tools and take the necessary safety precautions. Let's get started!

Identifying Your Larson Storm Door Closer Model

The first step in adjusting your Larson storm door closer is to identify the specific model you have. Larson offers a variety of storm door closers, and the adjustment methods may vary slightly depending on the model. Your closer will likely have a model number printed on it, usually on a small label. Locating this number allows you to consult the manufacturer's instructions specific to your model. This is crucial because the placement and function of adjustment screws can differ. Failing to identify your model correctly might lead to incorrect adjustments or even damage to the closer.

If you can't locate the model number, take a clear picture of the closer and consult Larson's website or contact their customer service. They can help identify your model and provide you with the necessary instructions. You can usually find helpful diagrams and videos online as well, demonstrating the proper adjustment procedures for different models. Remember to always prioritize safety and be cautious when working with any mechanical device.

Adjusting the Closing Speed

One of the most common adjustments needed is controlling the speed at which the door closes. A door that slams shut aggressively can be jarring and potentially damaging. Conversely, a door that closes too slowly might not latch properly, leaving gaps for drafts and compromising security. Most Larson storm door closers have an adjustment screw that controls the closing speed. This screw is often located on the body of the closer itself, and it is typically a small, slotted screw.

To adjust the closing speed, locate this screw and carefully turn it clockwise to slow the closing speed or counter-clockwise to speed it up. Make small adjustments at a time, testing the door's closure after each adjustment. A quarter-turn is usually sufficient for a noticeable change. Remember to always test the door after each adjustment to ensure you achieve the desired closing speed. Over-tightening the screw can damage the mechanism, so proceed with caution.

Adjusting the Latching Force

The latching force is the strength with which the door latches closed. Insufficient latching force can lead to the door not closing completely, resulting in drafts and security vulnerabilities. Excessive latching force, however, can make it difficult to open and close the door, potentially causing damage to the door frame and closer mechanism over time. The adjustment for latching force is usually a separate screw from the closing speed adjustment.

Similar to the closing speed adjustment, this screw is often found on the body of the closer. Turning this screw clockwise usually increases the latching force, while turning it counter-clockwise decreases it. Make incremental adjustments and test the door's latch after each adjustment to find the optimal balance between secure closure and ease of operation. A properly adjusted latch should close securely but not require excessive force to open.

Addressing Back-Checking or Delayed Closure

Sometimes, a storm door might exhibit back-checking – a slight pause or hesitation before the door finally closes. This can be caused by a variety of issues, including incorrect adjustment of the closer, worn parts, or obstructions in the door's path. If your door is experiencing back-checking, first check for any obstructions such as rugs or debris that might be hindering its movement.

If no obstructions are present, you might need to fine-tune the closing speed and latching force adjustments. Slightly increasing the closing speed can often alleviate back-checking. However, if the problem persists, it might indicate a more serious issue that requires professional servicing or replacement parts. In such cases, consulting the manufacturer's instructions or contacting a qualified technician is advisable.

Troubleshooting and Maintenance

If you've adjusted your Larson storm door closer according to the instructions and the door is still not functioning correctly, there might be other factors at play. Worn-out parts, such as the springs or seals within the closer mechanism, can impact performance. Regular lubrication of the closer's moving parts with a light oil or silicone spray can prevent wear and tear and improve performance.

Inspect the door's hinges and rollers for any signs of damage or wear. Loose hinges or damaged rollers can also contribute to erratic closure. Tighten any loose hinges or replace damaged rollers as needed. Remember to always consult your specific Larson storm door closer’s instruction manual for detailed troubleshooting and maintenance guidelines. If you continue to experience problems after trying these steps, it is best to contact a professional for assistance.

Safety Precautions

Before attempting any adjustments, ensure that the power to any nearby electrical outlets is turned off to prevent accidental shock. Always wear appropriate safety glasses to protect your eyes from any potential debris or springs. If you're unsure about any part of the adjustment process, don't hesitate to consult the manufacturer's instructions or seek professional help. Working safely is paramount.

Remember that improperly adjusting your storm door closer could lead to damage to the door, closer, or even injury. Proceed with caution and take your time. If you are uncomfortable performing any of these adjustments yourself, it’s always best to call a qualified technician. A small investment in professional help can save you time, money, and potential frustration in the long run.
