Hi everyone. I have a Carrier furnace that is behaving erratically. It works during the day when the temperature is not too cold but it does not work at night when it is cold. I went to the attic to check it and I see the blinking led but I am not sure as to how to figure it out. The sequence seems to be short blink, long blink and immediately three short blinks.
