My spring operated roller shade won’t go up all the way.
You need to increase the tension on the internal spring. With the shade mounted in the window, pull it down half way and then remove it from the brackets. Roll up the shade by hand. Be careful to roll it up evenly. Remount the shade and test the tension.
My spring operated roller shade goes up too quickly and has too much spring tension.
You need to release some of the tension on the spring. Remove the rolled up shade from the brackets. Unroll it several turns by hand. Remount in the brackets, and test the tension.
