Access electronics can repair the board. Copy the software first. We had one a while back that would fault out with an over torque at one floor, and it was a hoist way door issue causing it.
It did take a little bit of work and a custom pulley, we replaced another one with a motor and board from a linear GAL MOVR. Kept the mechanics of the existing operator. Did not have to do a full mod, just alteration permit. Really do love those GAL board and motor set ups.
