Troubleshoot Lift Problems with Blinds or Shades
The Cord Lock Mechanism is a snap-in part. The mechanism may be defective if the roller pin is prevented from moving freely.
- Make sure the blinds lift cord runs straight up into the cord lock mechanism with no obstructions or diversion. The lift cord should not be twisted
- When the blind is lowered, the roller pin should be loose to the touch.
- The roller pin must be able to move freely up and down on the truck.
- Make sure that the lift cord is not caught between the lift cord mechanism and the headrail when the lift cord mechanism is snapped into the control route/punch in the headrail.
- Small blinds (less than 20-1/8" net width) and blinds with same-side controls have a tape roll support near the cord lock mechanism. This closeness may create tension on the lift cord if the lift cord rubs against the tape roll support
- The curved tabs that secure the cord lock mechanism under the lip of the headrail can sometimes become bent after use. To create a more firm hold: remove the cord lock, bend the tabs upward, and replace the cord lock
