You can safely check a few things before calling. With the opener disconnected (pull the release cord), see if the door moves smoothly by hand across its full travel - binding at one spot usually points to the exact section of track that's bent or a bracket that's loose. Look at the rollers where they sit in the track; a roller with a chewed-up or missing nylon edge is an easy, cheap swap and a fair job to hand to a handy homeowner on a non-torsion door.
What we don't recommend doing yourself is anything that involves disconnecting cables, moving the door while a spring is still under tension, or re-bending track that's holding weight. A door that's partway off its track can still be carrying full spring tension on one side, and that's enough force to take a finger or drop the door suddenly. If the door won't move by hand at all, or it's leaning visibly in the opening, that's a call-us situation, not a weekend project.
If you do swap a roller yourself, run the door through several full cycles afterward and watch the track the whole way - any new noise or hesitation means something else got knocked out of alignment and it's worth a second look before you trust the door with the car underneath it.
