kitchen cabinet door
 

One of our cabinet doors won't close properly. Is there a screw that should be adjusted?

Maybe
 

Sometimes depending on the hardware used you can adjust how the door sits.

Had to get new hardware ar Home Depot

sometimes a little wedge is needed

Maybe.
Look to see if any of the holes are slots instead of round. This leaves you a little room to adjust.
Try loosening all the screws. 2 or 3 turns. The door should be a little lose. See if you can close the door and adjust it as you would like it and then try to open with out moving and tighten the screws. Even with round holes only it might work if you are only out a little bit.
