Flashing Green Light. A flashing green light on your Ruud furnace typically indicates that it is in diagnostic mode or going through its startup sequence after being powered on or reset. During this time, the system runs various checks to ensure everything is working correctly before proceeding with normal operation.. A blinking green light on a furnace typically indicates that the furnace is operating normally, and the light is simply showing that the furnace is in the middle of a heating cycle. However, it's always a good idea to check the furnace's user manual or contact a professional to confirm that this is the case for your specific furnace model.
