Keystone Montana RV Roller Shade Repair & Replacement Parts

A shade that will not stay at an intermediate position needs identification and diagnosis before a replacement part is selected. The Keystone Montana coach name and the unsuccessful earlier repair do not establish which shade mechanism is installed, that the auto-stop is faulty, or that the ordered part was wrong.

Record the shade manufacturer, model/label, mechanism type, tube outside diameter and the original and replacement part numbers. Photograph the roller ends, controls and both parts, and describe whether the shade fails to hold at every position, stops at the wrong upper height, or rises at the wrong speed. These are different observations; tube size alone does not identify the failed component.

For an identified Irvine Slow-Rise shade, the manufacturer's operating guide describes holding at the chosen lowered position and releasing with a short tug to rise to the upper stop. It separately identifies upper-stop position and rising-speed adjustments. That guidance does not diagnose this unidentified shade or prove that changing an auto-stop will restore its holding function. Use adjustment or repair instructions only after confirming the matching mechanism.

Irvine's official parts reference distinguishes Slow-Rise auto-stops from Valu-Line 1-inch and 3/4-inch versions. Our RL-A3100 Slow-Rise listing and MRL-A2500 1-inch Valu-Line listing are separate identification references, not confirmed Montana repairs or interchangeable parts. Have the identified mechanism assessed before opening a tensioned spring assembly. Send the label, photos and part numbers for comparison before purchasing another component; no repair result or order remedy is promised here.
