When powering doors by placing a Redstone Block/Torch/et cetera adjacent to them, the doors are not unpowered when the block is removed via commands using the replace function. They properly become unpowered when using the destroy function, however. This applies to all doors, trapdoors, and fence gates.

Steps To Reproduce:
1) Place any two doors.
2) Place one Redstone Block next to each door.
3) Remove one Redstone Block using /setblock ~ ~ ~ air 0 replace.
4) Remove the other using /setblock ~ ~ ~ air 0 destroy.

Step three will not unpower the door. Step four will. Other redstone devices work correctly- as far as I've tested- and unpower upon removal.
