Window or door won't open, close, or lock properly
Likely cause, what to safely try first, and whether it gets worse if you wait.
Likely cause
A warped frame or a misaligned track/rollers.
What to try first
- Check if it's worse in humid weather — that points to a warping frame rather than hardware.
- Clean the track/rollers of debris before assuming a part needs replacing.
