Question About Craftsman Garage Door Opener 139.539850
Stops mid close or open cycle...

Opener will stop mid open or close cycle. sometimes the power will go off or the lights will flash off and on several times. Power source input is steady; sensors, main console, and security pad lights are on. Could this be a logic board problem?
