Window Crank Handle Spins But Won’t Open Window?
Posted in Window Parts, on May 29, 2025
Crank windows are extremely popular because of their flexibility and ease of use. They allow homeowners to open their windows to whatever extent they choose, letting them experience fresh airflow. The only issue is that crank handles can break very easily, making it difficult to open your window once they are broken. One of the most common issues with damaged window crank handles is when they spin but won’t open. Although this can be frustrating, there are ways to fix the issue by replacing damaged parts with Amesbury Truth Hardware. If you are struggling with any kind of window mechanisms, shop Window Hardware Company’s many replacement parts online.
Here are some reasons why your window crank handle spins but won't open.
How Does a Window Crank Handle Work?
Crank windows operate using a mechanical system made up of a crank handle, a gear-driven operator, and one or more arms that connect to the window sash. When you turn the handle, gears inside the operator rotate, which extend or retract the arm to push the window open or pull it closed. If any part of this mechanism becomes damaged or fails, it will prevent it from operating properly.
Common Reasons Your Window Crank Spins Without Opening
When your window crank handle spins but will not actually open, this is a sign of some kind of damage or issue inside the mechanism.
Stripped Gears in the Crank Mechanism
As time goes on, the gears inside the window crank mechanism can wear down and become stripped from the friction when in use. The majority of crank handle gears are made of either plastic or rubber, both of which can corrode or break down due to extensive or inappropriate use of the crank. Once this occurs, the gears will no longer be able to grip onto one another, preventing the crank mechanism from working at all. This is why the crank will move, but the window won’t open. Since it is very difficult to repair worn-down gears, the entire window crank handle usually needs to be replaced in this situation.
Disconnected or Broken Operator Arm
Another reason why your crank handle may crank without the window opening is if the operator arm is damaged or disconnected from the rest of the mechanism. The operator arm is the part of the window that pushes it open and closed. If the arm of the window is broken or, for some reason, is disconnected from either the crank or the window sash, the window will not open. The good news is that this issue may be easily fixed. If the arm is not broken and is simply detached from the window, it can be reattached. However, if the arm is broken, it will need to be replaced. Amesbury Truth Hardware is an excellent option for all types of window cranks.
Crank Handle Is Loose
Sometimes your window won’t open simply because the crank handle itself is a bit loose. Crank handles are connected to the crank mechanism with a screw. Over time, the screw can naturally loosen. This will cause it to spin loosely and with no tension. If you tighten the screw, it will restore the resistance that allows the handle to open the window.
