The elevator door gets stuck in the open position when it arrives on a given floor or two, only resetting it or restarting it gets it to work again, none of the buttons work when this happens and the panel lights go dim (floor number, etc)A building maintenance guy mentioned something about a reset button that kept popping when this happened...
The two codes I have seen flashing on the box are, I believe F1 0021 and 0065.
Thanks!
Replace ADON board
thanks for everyones replies.
PS the kone guy was here today, I had to leave before he finished but it is working at this time...
Stairs are ok but 2 years takes a toll on the knees, with a dog that's many extra trips. The kone tech did fix it-- so it is fine for now. Hoping is lasts! Really wish I catch him sometime again to learn more.
