I have 2 Craftsman security 139.53681 gdo's. Gdo 'a' works with remote 'a'. but will not work with remote 'b'. Gdo 'b' will not work with remote 'a' and will only work with remote 'b' when the light bulb times out. If the work light is on the remote will not work. I do not have the door switch with the light control or lock. Help.
