Here are the top signs your window crank is failing.
1. Difficulty Turning the Handle
A great deal of resistance when trying to open your window is not normal and could indicate a number of issues with your window crank mechanism. It may feel like your window crank is sticky and requires a lot of extra force to open. This could be a sign that your mechanism is rusted, the gears are stripped or that something is stuck inside the crank.
2. Grinding or Clicking Noises
If you hear grinding or clicking noises when operating the crank, this usually means that one of the internal components is worn, damaged or misaligned. Misaligned gears can cause a grinding sound, and they can wear down when you force your window open. In this case, it is best to avoid using the window crank and look into investing in replacement parts.
3. Window Won’t Fully Open or Close
If you crank your window and it doesn’t actually open or close, the mechanism is definitely failing. In this case, you may find the window only opens halfway and does not entirely seal shut when closing it. This can lead to drafts and poor energy efficiency down the line, not to mention that this is a major security issue. Being prompt with replacing your window crank in this scenario is crucial.
4. Crank Handle Spins Freely
A crank handle that spins freely without moving the window usually points to stripped internal gears or a disconnected operator mechanism. This means the force from the handle is no longer being transferred to the window arm, so the system has effectively failed. In most cases, this issue requires repair or full replacement of the crank mechanism to restore proper function.
5. Water Leaks During Rain
If your window appears to be operating properly, but is suffering from water leaks during rain, this may be a sign that your window crank is not creating a tight seal. In this case, the gears in your crank may be stripped, loosening the grip of your crank handle, preventing a tight seal.
