Guys,
I understood these steps have torque sensing motors. If that is correct, why don't they stop or reverse when they hit something.

When I worked on mine some time ago, I was trying to figure out what controlled it stoping in the open/closed position. I was told it was torque sensing, & that when the motor drew over a certain amperage it either stopped or reversed.

They do and mine was working. What happen was mine was out and I hooked it on a truck tire that was parked.
