The door won't open, or it opens a few inches and stops - that's the classic broken torsion spring, and on a Blanchard house built in the 1990s it's usually a first-time failure rather than a repeat one, since the original hardware on that era of construction tends to run longer before it gives out.
If the door opens but the opener strains, grinds, or reverses partway, that's a spring losing tension rather than one that's fully snapped - still dangerous to force, still worth a call before it goes all the way.
A door that slams down instead of lowering smoothly is often a sign the spring is failing, not the opener. Given the region's moderate heat rather than harsh winters, we don't see the extreme cold-snap spring failures some climates get - out here it's steady age and cycle count that does the wearing.
See the Blanchard garage door page for the rest of what we cover there, or check spring repair details for the Shreveport area if you're outside Blanchard proper.
