What happens if the room is cold and you selectively heat only the
bearings/gear box with hot air?
It keeps the grease from getting hard.
So clean off this cheapo grease and replace with cold-adapted
alternative?

Yes, that's by far the best idea but next to impossible to get to where the grease is without major disassembly. And that's nothing compared with putting it all back together again.... I did a partial disassy once before which took a good 2 days. Chair was originally installed on the right side of the stairs and had to move it later to another stairway on the left side. Everything had to be switched to the other side. I still can't believe we did it and got everything back working.
