What Does the Flashing Light on My Heating System Mean?

Your furnace depends on lights to flash code when it requires repairs. It also uses these lights to let you know it’s operating properly.

Normal function involves:

  • Concurrent slow flash—heater working like it should.
  • Both lights flash fast—heating system is beginning to call for heat.

If you realize that a solitary light going on and off slowly and the other blinking rapidly, your heater could have a low flame signal. This can happen even when your heating system is heating properly. It indicates the flame sensing rod may be dirty or in the wrong location on the burner. Contact us at 720-613-2210 for support.
