How To Fix Jamming Door Handles
Why Are My Door Handles Jamming?
Whether you are fitting a new door handle or are having problems with your existing one, you might be having problems with your handle jamming and not turning properly. Before you resort to buying a replacement, read our handy guide for tips and solutions.
What Are The Two Main Reasons For a Jamming Door Handle?
A sticking or jamming door handle is caused by one of two problems:
- An issue with the tubular latch/sash lock OR
- A problem with the handle.
In order to establish which is causing the problem, you will need to unscrew your door handles and temporarily remove your tubular latch/sash lock from the door.
1. Tubular Latch/Sash Lock Problems
A door handle is either fitted with a tubular latch or a sash lock. These are usually the main casue of any jamming problems and you will need to check for these faults:
- misalignment in the fitting of the latch/lock
- debris clogging the moving parts
- loose screws
- binding of the latch/lock parts due to the mortice fitting being too tight
For an easy way to check if there is a problem with the fitting of the latch/lock, take all parts and reassemble away from the door - if the lever handle moves freely without any problems, there is definitely a fitting issue. A common problem is where the lock/latch parts are binding against the timber. This can be rectified by making the mortice hole slightly larger and re-fitting.
2. Handle Problems
If you have checked all of the possible latch/lock problems above and the handle is still jamming, there may be an issue with the handle itself.
- debris in spring mechanism
- needs lubrication - WD40 is an ideal light oil for door handles
- broken spring
It may be that the spring in your handle is worn and old and in this instance the best advice is to replace the handles.
