I successfully replaced a broken plastic sprocket that was attached to the drive shaft of the motor, runs the chain to the screw jacks.
I failed to test the unit with trash in it, only tested without trash, and the motor reversed at the bottom and the ram returned to the top.
Now my customer has called and there is trash inside and its making the same noise it made right before the plastic sprocket snapped in two.
My question is this: Is there a switch inside the motor that senses when the motor is slowing and changes the direction of the motor? Would the P/N be W10439651?
It appears that the drawer switch and top switch seem to work, would it make sense that its the motor switch that is defective?
Thanks in advance.
