I recently picked up a building on my route and here goes. I’m working on a 12 stop Dover composite. It is a duplex, but whoever had them before me removed the top mounted selector and installed some kind of electronic one on elevator #1, that elevator is currently out of service and to my knowledge has been for some time. That isn’t the one I’m working on though, the one I’m working on has original selector on top and was operating fine until about 2 weeks ago when the down calls on floors 2, 3, and 4 stopped working. It would take an up call but no down call from those floors. All calls worked on other floors. Over the past 2-3 days this elevator has stopped working completely, then it started going to random floors when any call was given, then without changing anything would start going from top to bottom nonstop cycling doors at those landings. After cleaning the sleds and the top mounted selector and checking and cleaning all of the ibm relays carefully it started working properly for about 10 minutes then started going from top to bottom again no matter what call was given. Then all of sudden while I was going prints that are on jobsite but not clearly not for this particular job the elevator started taking up calls and going to designated floor just fine, on the down call it would go to the floor below the designated call, cycle doors then go up one floor to designated call. After about and hours or so of that it started stopping at every floor cycling doors no matter what call or which direction. After a 17 hour day I went home last night, came back this morning and it’s back to running top to bottom. I’m at a complete loss, and I’ve only got one other composite on my route at the moment so I’m not real familiar with these. Any and all advice is much appreciated. Work safe!
