What Does the Flickering Light on My Heater Mean?

Your heating system depends on lights to flash code when it is malfunctioning. It also engages this system to let you know it’s heating like it should.

Regular function includes:

  • Simultaneous slow flash—heater operating properly.
  • Both lights flash fast—heater is starting to call for heat.

If you notice a solitary light going on and off slowly and the other flashing rapidly, your heater may be having a low flame signal. This can take place even when your furnace is running like it should. It signifies the flame sensing rod could be dirty or in the wrong spot on the burner. Contact us at 251-471-2674 for support.
