Liftmaster 1/3 HP - humming, but does not open.

Door worked fine 1 hour prior to door not working. no storm, no electrical problems. overhead unit gets power - light comes on. Press either remote or wall remote and unit clicks, then hums for about a second or two, then stops humming. Door is not jammed - works fine when released. Motor turns freely when manually turned (so it's not locked up). Circuit board problem or transformer? any ideas? thanks
