What is a Flashing Air Conditioning Light?

Newer air conditioners come with an outdoor unit circuit board that is technologically designed to protect the system which is why you might notice a green light flashing on and off. A sudden spike in the power supply can cause overvoltage, this might cause the ac unit to go to shutdown mode, hence the green light will start flashing. This is an auto-response aimed at protecting the unit from damage due to the increased voltage.

For a multi-split system, another reason to consider is mode settings, all the indoor units should be on a similar mode, having the units on different settings could cause shortcomings making the aircon not function and you might see a flashing green light. Other probable causes could be damaged power chords, issues with the fan or the refrigerant, all of which might require the services of an experienced technician.
