Inside the main (West) elevator, the LED display of the current floor is blank. Apparently the LED controller has failed. The problem has been outstanding since at least mid-December 2016 despite having been reported to the library by at least three patrons about a dozen times in all.
This causes problems because if a passenger enters on the 5th floor and presses the button for the 1st floor, if the elevator door opens, the assumption is that the 1st floor has been reached, even if what actually happened was the elevator stopped at the 2nd floor for a new passenger, and I have, and have observed other people, exit the elevator thinking we’ve reached our destination, only to find ourselves on the wrong floor.
(Resolved sometime in June, 2017.)
