From a cold start with the door down:
With the first push the light comes on, but door will not move. No sound is heard.
Second push: nothing as with the rest of the pushes.
After disengagement of the carriage and moving it off of the switch:
First push: The door motor starts and the screw rotates in the direction of pushing the door down.
Second push: stops the motor.
Third push: The door motor starts and the screw rotates in the direction of pushing the door down. Yes "down" no reversal of the motor.
After replacing the sequencer board with one from an operational unit same results only it won't go down, but it will go up. Is there something in the motor that isn't reversing? Could there be an open wire between the board and the motor?
I swapped capacitors and there was no difference in either unit. Could the transformer cause this? I've checked continuity between all wires except inside the motor. They all check fine. The continuity checks the same for the part on both units' parts i.e., capacitor and transformer. The transformers are grounded. I'm at a loss.

You might want to search Google to find a Genie forum, or any forum about repairs of this nature. Most of us around here are into living frugally, but not necessarily complicated repairs such as that which you describe. You obviously know quite a lot about this already, so you need to find people who know even more than you do. Some sort of DIY forum is more apt to yield answers for you, I would think. :)
Can someone help troubleshoot? Our Sears garage door opener has been going up by itself without anyone pushing the remote or wall buttons. Also when we tried to open door one day it would go up part way and come right back down. I was finally able to get our car in the garage but now am afraid I won't be able to get it out without the door coming down on the car.
