I am brand-new to the forum. I'm a building owner in downtown L.A. Hoping that you can help in solving our elevator's selector problem.
1947 Otis, overhead traction
4 stops
2500 lbs. capacity
Machinery in good condition, considering age - not altered or "bastardized"
Selector type: "similar" to Otis 6104 Selector on Unitek website - "similar" but not a pie-plate
Problem Source: 100% pinpointed to Selector
Problem Description: goes to floor, seems to stop low, won't open, goes back to 1st Floor, then might go to any floor - and stops there, unopened.
