Hello and welcome to JustAnswer - My name is ***** ***** I'll be happy to assist you. In order to pull up the proper fault codes, can you please provide the model # of the condenser? It should be on a tag near where the copper lines enter the unit. Also, can you describe how the red and green lights are flashing? Together slow flash, together fast flash, alternating slow/fast flash, etc.
