Goodman furnace flashing green light
The Goodman furnace flashing green light occurs when the control board reads that there are no flames in the furnace. A potential error code can be a flashing green or yellow light on the control panel.
Goodman furnaces are a popular brand, widely installed in homes and businesses. On some Goodman furnaces, when the burner fires up, the green light flashes. There is no need to worry if this happens to your furnace, as it’s completely normal behaviour for your Goodman furnace.
The reason for this is that the green light shows you that the ignition system has been activated and working correctly.
It’s important to realize that a flashing green light does not necessarily mean an issue with your heating system or furnace.
The Goodman Furnace flashes the green light after it is preheated.
This is done to ensure that the heat exchanger section of the furnace is working properly.
The green flashing light indicates that the furnace has started a self-diagnostic mode and will check if everything is in order.
If there are any problems, you will see an error code on display and a red flashing indicator light instead.
Typically, this means something is wrong with your circuit board or power supply.
