It is a screw type, a Genie Pro 88, for what that's worth. There are no electric eyes.
After I lubed it, it would start to open the door but only travel about twelve inches, then it would reverse itself, as if it had hit an obstruction, and then go back to the beginning position, where the door is closed. After some time I tried it again and it worked. Then, later it did the false start, stop, and return to Go routine. This morning, it opened the door, I drove out, hit the remote, nothing happened. I ended up disengaging it and closing the door by hand. After I closed it by hand, I reengaged it. When I returned home, it did not open. I opened the door by hand, reengaged it, tried it while looking at it. The motor comes on for a brief period, then shuts itself off. I removed the housing and observed the clutch at the back. When the motor gets the signal from the transmitter it comes on but there is no clutch movement. I am wondering if the many false starts, stops, and returns perhaps stripped something inside.
