Is a crack in sheet rock possible foundation problem?

[Deadrick Colbert]

Would a 3 inch horizontal crack in sheet rock be anything to worry about? Someone mentioned settlement and that I should have the foundation looked at. There is no visible problem to the outside brick or concrete. Could this really be a big deal?

Tough to say, but I lean towards no. My previous personal residence was a 1987 built colonial. Every year that house would get cracks in a bunch of places. Master bath at the corner of the door and window. The main floor would get one across the ceiling where the front hallway is. In the winter/summer they would open/close. The house had no foundation issues, it just settled some over the years and these areas showed signs.
