Hello! First! I'm new... Wait for others advice lol
Okay! On the experience I had with Phalaenopsis that didn't bloom, was lack of nutrients or bad media.
Did you repot the orchid and put it on a new fresh airy media recently?
I also read tons and read blooming is affected by light and temperature, another member mentioned that recently to me too, but I have a really bad memory, hopefully someone can provide you more information but I would look at this points once you check for sure that the whole plant is healthy, then it might be the temperature or the media it is in.
Good luck!
