Opener closes, won't open

My GeniePro 951 C/A recently started having this problem. It would close but not open. I finally figured out that, once it closes, if I free the door from the track with the emergency release, open it just a bit and reattach the door to the track, then unplug and replug the unit it would open easily. I could even close it most of the way with the remote or wall control, then reverse it before it hit the close limit switch and it would open just fine. BUT, if it ever hit the close limit switch, it was as if it created a short. Once I went through all the above steps again it would start working... until it hit the close limit switch again. I swapped out the close limit switch with one from the other garage door but it made no difference. I reversed the close switch with the open limit switch ( they are exactly the same) but that didn't change anything. I have concluded that it is not the switch itself, but rather once the limit switch is hit, it trips something in the controller. Unplugging and replugging the unit "reboots" it ONLY if the door is raised by hand to free up the close limit switch. Everything inside the controller is nice and tight and clean. I suppose it is a relay or something that has gone bad. Any suggestions before I call out the repair guy?

Try adjusting the close limit to where it doesn't quite close completely and see if it then will operate on both cycles. If so, gradually readjust the close limit to where it belongs but not too far.

I've been to Genie's web site. No help. I've adjusted the settings. No help. Before the door actually trips the close limit switch, I can push the switch with my finger and it will stop the close, but this totally shorts out the opener, until I reset it by unplugging the unit and plugging it back in. Because I can do this just by touching the close limit switch I do not believe it has anything to do with the open and close adjustments. It must be a short out in a capacitor or relay that is triggered by the close limit switch. I've called a Genie authorized service company, the one's who installed the unit. I'll post back what the outcome is.

Make sure the switch on top of the wall controller is in the correct position. After I installed a new Genie I had the same problem. I was ready to take it back to the store when I found the switch was in the vacation position.
