    Hello, thanks for any response.. here's my problem: rail driven "Genie" opener, door is disconnected from the operator and the motor seems to working properly.

    I engage the opener and it goes up/down slightly, with a violent vibrating action then stops. The total range of motion is maybe 6 inches/ 1-2 seconds. Its not a grind, more like a sputter. I haven't serviced the unit yet (lubed), and the electric eye is unobstructed. When the plastic gear ("opto wheel" in this case) is exposed the rail twists freely.

    Any ideas? Much appreciated.

    Try pulling the "emergency" chain to unlock the door from the opener, and run the opener by itself. If that works, then the door is sticking somewhere. Check the "lock" on the door to make sure it's not in the locked position (metal piece through the side rails, about 18" above the motion sensors). If it's locked, just unlock it (move the metal out of the way) and it should work.

    Thanks Gurutech. I found some metal shavings on the screw drive itself and so inspected the trolley which as it is needs to be replaced. Still not the issue though since even when the trolley is disengaged the screw drive doesn't turn. I've tried manually spinning the drive via the main sprocket at the back of the operator with significant resistance after less that 1/8 a turn. I'm also hearing a humming noise so we will see. Going to inspect the motor and capacitor unit next to see what comes from that.
