The point in the travel where a door resists often tells a more useful story than the word stuck. A difficult first push, a catch at the same position and resistance only near the latch are three different observations. This collection helps you describe the pattern without forcing the panel or deciding in advance which part needs replacing.
Separate movement, sound and closure. Record each in its own words before connecting them.
01
Name the moment
Note whether the problem happens at the start, midway through travel or at the last few inches. If a door feels unstable, do not repeat the movement to make a recording. A stationary photograph and a description are enough to start the conversation.
02
Describe the pattern
A repeated catch in one location is different from a rough feeling along the whole travel. Say whether the condition is new, gradual or noticed after other work. These details help define an inspection; they do not prove which component failed.
03
Keep the opening in the picture
Include the frame, sill and adjacent panel in your description. Choosing a roller or lock from a symptom alone can miss an alignment or track problem. Use the individual guides to learn what additional observation would actually distinguish the possibilities.
