What Does the Flickering Light on My Furnace Mean?

Your heating system relies on lights to flash code when it isn’t working right. It also uses these lights to tell you it’s heating properly.

Correct heating includes:

  • Concurrent slow flash—furnace heating properly.
  • Both lights flash fast—heating system is starting to call for heat.

If you see a lone light blinking slowly and the other going on and off rapidly, your furnace may have a low flame signal. This can happen even when your heater is heating like it should. It signifies the flame sensing rod could have buildup or in the incorrect area on the burner. Contact us at 573-635-3547 for assistance.
