You can swap the board between openers to see if that is the problem. If it
is, the replacement board shouldn't cost over half the price of a new
opener.

Thanks for all the quick replies.
I disconnected the traveler from the door so there was no load on the opener
and it still does exactly the same thing. I re-checked the photo cells and
they are good. If I block the beam, the light in the receiver goes out.
Everything seems tight and well adjusted.
I think something has crapped out in the electronic guts of this thing.
