Symptoms
- Sash won't tilt in toward the room
- Release tabs feel stuck or won't move
- Sash tilts partway then jams
- Pivot pins visibly out of position
Likely causes
- CommonRelease tabs painted, dirty, or stiffSmall plastic or metal tabs at the top corners of the sash need to be pressed to release the tilt mechanism.
- CommonPivot pins misaligned in the frame trackIf the pins aren't seated correctly, the tilt mechanism can bind.
- PossibleBalance tension too tight or too looseAn improperly tensioned balance can make the tilt feel stuck even when the tabs release fine.
- PossibleDebris in the pivot trackDirt buildup at the top of the jamb track can block the pins from sliding.
What to do
- Locate the release tabs, usually small levers at the top corners of the sash, and press both simultaneously while pulling the top of the sash inward.
- Clean any paint or grime off the tabs if they feel stiff, using a small brush and mild solvent if needed.
- Check that both tabs release at the same time; uneven release can make the sash bind partway through the tilt.
- Inspect the pivot pins at the bottom of the sash for correct seating in the jamb track.
- Clear any visible debris from the top of the track where the pins ride.
- Lubricate the tabs and pivot points with a light silicone spray.
- Practice tilting the sash in and back out a few times once freed to confirm smooth operation.
Tools and parts
- Small brush
- Silicone lubricant spray
When to call a pro
Call a window repair pro if the release tabs or pivot pins are broken rather than just stuck, since those parts may need replacement.
