What Does the Flickering Light on My Heater Mean?

Your heater uses lights to flash code when it requires repairs. It also uses this system to relay it’s heating like it should.

Regular operation consists of:

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

If you realize that a single light going on and off slowly and the other blinking quickly, your furnace might be having a low flame signal. This can happen even when your furnace is working properly. It signifies the flame sensing rod could have buildup or in the wrong location on the burner. Call us at 601-736-7362 for help.
