I have been told that R’ Schachter and many others are Meikel using a Goy to push the elevator if there is a significant number of stairs. The logic is that it’s a Shvus (Amira L’akum) Dishvus (electricity) BeMakom Oneg Shabbos
Interesting. I had always thought (based mostly on hearsay, not actual sources) that the consensus of the Poskim followed the psak pf the Chazon Ish and R’ Shlomo Zalman, who held electricity to be a problem midi’Oraysa.
