Is that northeast window on the east side or the north side? I recommend east. A light shear curtain over the window will prevent direct sunlight from burning the phal early in the morning, but still allow enough light for it to grow and bloom. I keep reading that a growing orchid that has not re-bloomed probably needs more light. Is this new location brighter than where the phal was sitting before? If yes, then it is a case of hurry up and wait! It will bloom when it is ready.
