I got creative. I reversed the motor plug with a little help from a knife to remove the tit that prevents the plug from being put in backward. Works like a charm! Bizarre but everything is now programmed and my door works great. Since the motor is DC simply reversing the polarity did the trick.

There is no need to replace the spring as your door is balanced and this is a good check of spring condition. Something is wrong with your sensors. That is the only thing that will cause the main light to flash 10 times. Make sure the brackets at the door are solid and can't move as the door travels. The blinking of the lights on the sensors is so slight that you may have to get on your knees to see it. The wiring may have a break in it. Try moving it as the door closes. This will be difficult. If you can do a continuity check it would be better. If everything checks out it may be the logic board but I really doubt it.

I think it's time for a service technician. Be sure to give them all this information.

First, release the door from the opener, there should be a pull-rope hanging down from the trolley, and operate the door manually to help determine if the problem is the door or the GDO.
