Hello I am here to assist you.
The red LED light inside of your furnace is there to communicate with you the home owner.
It is there to tell you if the furnace has a problem.
If there is a problem, the red LED light will blink in a certain pattern such as 1 blink pause, 2 blink pause, etc...
What kind of problem.
For instance if the furnace overheats and a High Limit switch shuts down the furnace, the red LED light will communicate that to you. It is very helpful in troubleshooting when your furnace malfunctions.
A steady blinking light means normal operation on a call for heat.
So you have no worries.
