What Does the Flickering Light on My Furnace Mean?

Your heating system depends on lights to flash code when it requires repairs. It also engages these lights to tell you it’s operating like it should.

Correct operation consists of:

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

If you notice a lone light blinking slowly and the other blinking rapidly, your furnace may have a low flame signal. This can occur even when your furnace is running correctly. It indicates the flame sensing rod may need to be cleaned or in the wrong spot on the burner. Reach out to us at 662-281-1231 for support.
