What Does the Blinking Light on My Furnace Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also engages this system to relay it’s operating correctly.

Normal operation includes:

  • Simultaneous slow flash—furnace working correctly.
  • Both lights flash fast—heating system is beginning to call for heat.

If you realize that a solitary light blinking slowly and the other going on and off fast, your furnace might be experiencing a low flame signal. This can occur even when your furnace is operating like it should. It indicates the flame sensing rod could be dirty or in the incorrect spot on the burner.
