What Does the Flashing Light on My Heating System Mean?

Your heating system relies on lights to flash code when it is malfunctioning. It also works this system to tell you it’s operating like it should.

Regular heating includes:

  • Simultaneous slow flash—heating system heating like it should.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you see a lone light going on and off slowly and the other flashing rapidly, your heating system may have a low flame signal. This can happen even when your heater is working like it should. It indicates the flame sensing rod might need to be cleaned or in the incorrect location on the burner. Reach out to us at 760-784-9034 for assistance.
