Symptoms
- Cord won't release to lower the blind
- Blind stays up no matter how the cord is pulled
- Cord lock feels stuck when you try to release it
- One side lowers while the other doesn't
Likely causes
- CommonCord lock stuck in the locked positionDust or wear can keep the small lock mechanism from releasing.
- CommonTangled cords inside the headrailCords can twist together, preventing smooth movement in either direction.
- PossibleCord caught on the tilt mechanismCordless tilt wands or mechanisms can interfere with the lift cord path.
- Less commonBent headrail or bracketA slightly bent mounting bracket can bind the internal mechanism.
What to do
- Try pulling the cord slightly to one side while releasing it, since the lock sometimes needs a specific angle.
- Tap the headrail gently while pulling the cord, which can dislodge a stuck lock mechanism.
- Remove the headrail cover if accessible and inspect for tangled or crossed cords.
- Carefully untangle any crossed cords by hand, keeping track of which cord goes where.
- Clean out dust and debris from the cord lock with a small brush.
- Check that the blind is mounted level; a bracket that's slightly bent or uneven can bind the mechanism.
- If the cord lock itself is broken, a full restringing kit typically includes a replacement lock.
