What kind of controller is it? Sometimes codes are controller specific, rather than unit make specific.. Common crown codes are in hundreds. so the 3 flashes may be different numbers. Unless you are getting solely a "3"

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
