We're based in Bartlett, about 8 miles from Millington, and that's the drive every call here involves - there's no local branch to dispatch from closer. Tell us what the door is doing: won't open, opens partway and stalls, makes a bang and drops, or the opener runs but the door doesn't move. That tells us whether we're loading a spring kit or a logic board truck stock before we leave.
If you're not sure what's wrong, that's fine too - describe the sound and when it started. A door that worked yesterday and locked up overnight is almost always a spring or a cable, not the opener. Have the make of the opener handy if you know it; it saves a trip back for the right part.
