RV Slow Rise Shade Stop Spring Repair & Latching Mechanism Help

A shade that will not stay down after a part was changed does not, by itself, identify a failed spring or prove that more spring tension is needed. First confirm the actual manufacturer, model/revision and the part that was installed. Do not use the earlier suggestion to wind an unidentified spring several more turns as a repair procedure.

For an identified Irvine Slow-Rise day/night system, the manufacturer's operating instructions describe lowering the bottom rail to the desired position and releasing it so the shade remains there; a light, short tug releases it to rise. The same sheet identifies a clear upper-stop-position control and a separate black speed control. Holding at a lowered position, setting the upper travel limit and controlling rise speed are different functions. This does not establish the internal failure or the correct adjustment for the unidentified shade in the question.

The RL-A3100 auto-stop listing and RS-SR31 spring-family listing are identification references, not interchangeable remedies. Irvine's replacement-parts guide separates Slow-Rise from the two Valu-Line tube families and shows distinct auto-stop assemblies. A nominal 1.25-inch description or a similar-looking end does not approve either part for an unknown system.

Compare the original label, installed part number, end profiles/engagement, controls, tube outside diameter and finished shade width with exact manufacturer documentation. Have a qualified technician identify damage and the applicable service procedure before removing or changing a tensioned assembly. The need for an auto-stop, spring, other component or complete shade—and the resulting repair—remains unconfirmed.
