How to Replace an Andersen Casement Window Crank: A Step-by-Step Guide

Whether your window crank has become worn out or is no longer functioning properly, replacing an Andersen casement window crank can be a simple and cost-effective solution. In this comprehensive guide, we will walk you through the process of replacing your window crank, ensuring that your window operates smoothly and efficiently once again.

Identifying Your Andersen Casement Window Crank

Before you can begin the process of replacing your window crank, it's essential to identify the specific type of Andersen casement window crank you have. Andersen offers a variety of casement window cranks, including the 400 Series, 200 Series, and A-Series. Each series has its unique features, so it's crucial to determine which one you have before purchasing a replacement.

To identify your casement window crank, look for a label or sticker on the window frame, which will typically indicate the series and model number. If you can't find this information, you can also consult your original product documentation or contact Andersen customer support for assistance.

Gathering Your Tools and Materials

Before you begin the replacement process, make sure you have the necessary tools and materials on hand. You will need the following:

Replacement Andersen casement window crank (compatible with your specific window series)

Screwdriver (Phillips or flathead, depending on the type of screws used in your window)

Allen wrench (for removing the handle)

Needle-nose pliers (optional, for removing the snap ring)

Lubricant (optional, for ensuring smooth operation)

Removing the Old Casement Window Crank

Once you have gathered your tools and materials, you can begin the process of removing the old window crank. Follow these steps:

1. Remove the window handle: Locate the small set screw on the base of the handle. Using an Allen wrench, loosen the set screw and carefully remove the handle from the crank.

2. Detach the crank cover: Depending on your specific window series, the crank cover may be held in place by screws or may simply snap into place. If your cover has screws, use a screwdriver to remove them. If your cover snaps into place, use a flathead screwdriver to gently pry it off.

3. Remove the crank: With the cover removed, you should now see the window crank mechanism. Use a screwdriver to remove the screws securing the crank to the window frame. Carefully lift the crank away from the frame, taking care not to damage the window or surrounding components.

4. Disconnect the operator arm: The operator arm connects the window crank to the window sash. Depending on your specific window series, the operator arm may be secured with a snap ring or a screw. If your operator arm has a snap ring, use needle-nose pliers to remove it. If your operator arm has a screw, use a screwdriver to remove it. Once the operator arm is disconnected, you can fully remove the old window crank.

Installing the New Casement Window Crank

With the old window crank removed, you can now install the new one. Follow these steps:

1. Attach the new crank: Position the new window crank in the same location as the old one, aligning the screw holes. Use a screwdriver to secure the new crank to the window frame with the provided screws.

2. Connect the operator arm: Reattach the operator arm to the new window crank, either by securing it with a snap ring or screw, depending on your specific window series.

3. Reinstall the crank cover: Place the crank cover back over the new window crank, ensuring it is properly aligned. If your cover has screws, use a screwdriver to secure it. If your cover snaps into place, gently press it until it clicks into position.

4. Reattach the window handle: Align the handle with the new window crank and slide it into place. Using an Allen wrench, tighten the set screw to secure the handle.

5. Test the new crank: Open and close the window several times to ensure the new crank operates smoothly and efficiently. If necessary, apply a small amount of lubricant to the crank mechanism to ensure optimal performance.

Maintaining Your Andersen Casement Window Crank

To keep your new Andersen casement window crank functioning at its best, it's essential to perform regular maintenance. This includes cleaning the window tracks, lubricating the crank mechanism, and inspecting the components for signs of wear or damage. By taking these simple steps, you can extend the life of your window crank and ensure your window continues to operate smoothly for years to come.

In conclusion, replacing an Andersen casement window crank is a straightforward process that can greatly improve the functionality of your window. By following this step-by-step guide and performing regular maintenance, you can ensure your casement window remains in excellent condition.

INSPIRATION & SOLUTION

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.

Simulated Hung Window with Tilt & Turn Openings

The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.

Why choose the tilt and turn opening method?

Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.

Large Energy Efficient Fixed Windows

Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.

Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.

Every window’s placement and shape not only add to the uniqueness of this home but also provide a more energy-saving ability for the owners.

Doorwin energy-efficient integrated glazing units feature double-pane glass, warm-edge spacers, argon gas fill, Low-E coatings, and fully tempered glass, they can not only create a comfortable and natural indoor environment but also save electricity bills and heating bills of more than 100 USD for the owner, it’s a real bargain compared to choosing a regular glazing set.
