How To Troubleshoot Blinds Lift Problems
If you are having lift problems with your blinds, it might be due to a Cord lock mechanism malfunction. It might be defective if the roller pin can't move freely. Fortunately, the cord lock mechanism is a snap-in part. Here's what to do:
- Verify that the lift cord is unobstructed. It should have no twists or diversions, and should run straight into the cord lock mechanism.
- When you lower the blind, feel the roller pin to verify that it is slightly loose when you touch it. The roller pin needs to move freely up and down along the track.
- The roller pin must be able to move freely up and down on the truck.
- Check that the lift cord is not stuck or trapped between the lift cord mechanism and the headrail, when the lift cord mechanism is snapped in place in the control route/punch in the headrail.
- If your blinds are on the small side (less than 20-1/8" net width) and or if they come with same-side controls, look for the tape roll support, which you should find near the cord lock mechanism. Sometimes tension is created because the tape roll support and the cord lock mechanism are too close together, and one rubs on the other.
- You might also want to check the curved tabs that secure the cord lock mechanism beneath the lip of the headrail. These tabs sometimes bend over time and usage. Fortunately, a bent tab is easy to fix. First remove the cord lock, then bend the tabs back into shape (upward), and finally put the cord lock back in its place.
