Quick answer
Lower the shade all the way, pull the bottom rail toward you at about 45°, give it three short tugs, then raise it. That resets the spring in the headrail. If it still drops, the spring is worn out.
Step by step
Step 1
Lower the shade all the way
Pull the bottom rail straight down until the shade is fully open and stops on its own.
Step 2 · side view
Pull it toward you at 45°
Hold the middle of the bottom rail and bring it out from the window at about a 45° angle.
Step 3 · side view
Give it three short tugs
Keep the angle. Quick and gentle, not hard. This re-engages the spring inside the headrail.
Step 4
Raise it, then let go halfway
Lift the shade and release it in the middle of the window. If it holds, you're done.
Why it happens
Cordless shades hold their place with a spring motor inside the headrail. Raising the shade too fast, pulling from one corner, or the fine desert dust that settles into Las Vegas headrails can knock the spring out of balance. After enough years the spring simply wears out, and no reset will bring it back.
Still dropping?
It may be time for a new shade
A worn spring can't be fixed at home on most shades. We measure every window for free and bring cordless and motorized samples to you.
Common questions
Can I replace the spring myself?
On most brands, no. The spring is sealed inside the headrail, and opening it usually ruins the shade. Replacing the shade is often cheaper than a repair.
Why does my shade only drop on one side?
One lift cord inside has slipped. Lower the shade fully and do the 45° reset, which lets both cords settle to the same length. If it is still crooked, that cord has worn.
Will this work on my brand?
Most cordless cellular shades use a spring motor and respond to this reset. If yours has a button or a wand on the headrail, it uses a different mechanism. Call us and we'll walk you through it.
