Will a sofa 89x39x39 fit through a 36x80 door?

There is a good possibility that it can, there are some details that you should be aware of:

• some sofa have detachable arms
• some have detachable legs

Even if the sofa does not have the above options the design of the arms of the sofa will be your biggest hurdle, try to pass it through the opening at a diagonal, hopefully the clearance on each side of the doorway will not obstruct your move. You can also gain some doorway clearance by removing the door and or doorstops/jams.
