If the remotes all quit working at the same time than yes you need a new logic board. On it will be a new receiver which is the other thing it might be. The only thing else it could be is if they will not close the door but will open then it is the safety sensors. If so realign them. If they will close the door but not open then check the wall station to make sure it is not "locked", if it is hold down the lock button for 3 seconds. But if they will not open or close then yes it is the logic board. You can go to sears.com, have your model # ready. There are personal shoppers who can guide you by phone, e-mail or chat. Thanks BB
