Hey David, so a flashing green light on a Carrier RV AC unit can mean a few things but it most likely is due to dirty coils that need to be cleaned which you would need to clean. It can also be low refrigerant which you would notice if it wasn't blowing as cold.

Hey David, did cleaning the coils on your Carrier AC fix the flashing light issue in your bedroom unit? Knowing what solved it could help others with the same problem.
