Craftsman GDO 139.18873 5 flash signal

I have just successfully completed the installation of a drive/worm gear kit. The info in your forum helped with some minor problems, thanks. On retesting the safety items and adjusting the up and down forces the manual suggested that I run the door through 3 or 4 cycles. I did this and the door stopped partway up on the 4th cycle. A green LED flashes 5 times on the back of the unit with a 3 second pause in between flashes. After 20 minutes or so the unit worked again but the flashing continues. Since then I have only opened and closed the door, not running it upand down more than once.

What does the 5 flash signal mean and do I have a problem? Any help would be appreciated. Thanks.
