What Is a Logic Board in a Garage Door Opener?
The Craftsman 1 2 Hp Garage Door Opener Logic Board is the electronic circuit board located inside the motor housing. Its primary role is to:

Without it, your opener can’t function. Think of the logic board as the “computer” that keeps your garage system running smoothly.
