What Does the Flickering Light on My Furnace Mean?

Your heater uses lights to flash code when it is malfunctioning. It also works these lights to relay it’s operating properly.

Regular heating consists of:

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

If you see a single light blinking slowly and the other going on and off fast, your heater could have a low flame signal. This can happen even when your furnace is working properly. It signifies the flame sensing rod might have buildup or in the bad location on the burner. Call us at 760-784-9034 for support.
