Craftsman Garage Door Remote Problem
I have an 11 year old Sears 139.53640SRT Garage Door Opener. A few days ago, all of the remotes stopped operating the door, but it still works normally from the wall switch.
The vacation lock is not on, and I have tried resynching the remotes.
The unit has a 41A4315-6C logic board, and the LED is flashing four (4) times.
Does anyone know the flash codes for this board?
If the board has to be replaced (~$75) I will probably just buy a whole new unit (~$150).
Any advice or insight would be greatly appreciated.
Thank you in advance.
