Troubleshooting 2020 Grand Design Imagine TT Value Line Shades

The reported failure to hold down does not identify a failed spring or a specific replacement part. Grand Design reference 691416, the coach year and the reported 26 x 17 inch dimensions have not been cross-referenced to an exact Irvine mechanism or service-part number.

First identify the shade manufacturer, mechanism and revision from its label and end assemblies. Keep shade width, fabric drop, bare roller-tube outside diameter and any assembly length separate. Record how the shade moves and whether the issue concerns holding a lowered position, the upper stopping point or raising speed. These are different functions; a black adjustment wheel alone does not identify the mechanism or the correct adjustment direction.

Irvine describes an upper-limit auto-stop feature on its Valu-Line shades and publishes separate Valu-Line and Slow-Rise auto-stop families. That does not diagnose this lower-position holding complaint. The current 1-inch Valu-Line MRL-A2500 listing and Slow-Rise RL-A3100 listing are identification examples only, not interchangeable parts or confirmed fits to this shade.

Use the applicable manufacturer's instructions after identification, or have a qualified shade technician inspect the mounting and mechanism. Do not follow the old generic tension-adjustment or spring-side disassembly advice for an unidentified tensioned assembly. No spring, stop or repair kit is diagnosed here, and no guaranteed repair or model-specific stock promise is established. Irvine Valu-Line reference.
