If your Irvine roll up shade won’t stay down in the closed position despite adjusting the open stop and speed, it is likely due to a worn or broken internal "auto-stop" or "position fixer" component. This small part is responsible for holding the shade in place when closed. Another possible cause is excessive spring tension causing the shade to retract automatically. The recommended solution is to replace the OEM Irvine 1.25" Auto Stop slow-rise roller shade component, which typically restores proper function. Ensure mounting brackets are secure but focus on the auto-stop mechanism for this issue. You can purchase the replacement part directly from Elkhart RV Parts to fix your shade quickly and reliably.
