What Does the Flickering Light on My Heating System Mean?

Your heater uses lights to flash code when it is malfunctioning. It also uses this setup to relay it’s working like it should.

Regular function involves:

  • Simultaneous slow flash—heater heating properly.
  • Simultaneous fast flash—furnace is initiating the call for heat.

If you realize that a single light flashing slowly and the other blinking fast, your heating system might be experiencing a low flame signal. This can happen even when your furnace is operating like it should. It signifies the flame sensing rod could be dirty or in the incorrect spot on the burner. Contact us at 662-269-8716 for help.
