What Does the Flickering Light on My Furnace Mean?

Your heating system uses lights to flash code when it isn’t working right. It also works this system to tell you it’s heating like it should.

Correct heating consists of:

  • Simultaneous slow flash—heater heating properly.
  • Both lights flash fast—heating system is beginning to call for heat.

If you notice a lone light flashing slowly and the other flashing fast, your heater may have a low flame signal. This can happen even when your heater is working properly. It signifies the flame sensing rod could be dirty or in the bad location on the burner. Reach out to us at 608-291-3606 for assistance.
