Run door is falling apart

[aart]

the 2×4 across the too of the door just split right down the middle length wise and the board near the hinge is starting to do the same

Was this due to where/how the screws were installed?

No, there were 2 knots in the center of the wood and it started cracking around them and chased the grain out to the edge. I'm guessing it was too much strain on a natural weak spot and it gave way.
