I have a weird issue with an old Dover of mine.
It started by blowing the fuse for door close, and after replacing the fuse, door close works fine, but... now the doors won't open on the bottom floor.
FS Phase 1 and 2 work as usual.
All calls at the other 2 floors work like they're supposed to.
But... When a call is registered at the bottom floor: the car runs down, gets to the floor, and stops, that's it. The call(s) stay latched, no gong, button remains lit, and can only be opened from the controller. 1C and 1U stay energized unless I manually reset the relays.
Any help?
