Could be an issue with the solenoid for down/unfold or the switches in the pendant went bad. I would first verify that you are getting signal from the pendant for the unfold and down functions, if so then go to the solenoid and verify that it is being energized. You also may have a ground detect switch out of alignment or going bad, in which case the down circuit would not work because it "thinks" the lift is already down. Those are the most common things I have run into with both Braun and Ricon lifts. If you need more info let me know and I will see what I can dig up on it, as I have access to the dealer side of things for Braun.
