What Does the Flickering Light on My Heater Mean?

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

Correct heating consists of:

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

If you realize that a lone light flashing slowly and the other going on and off quickly, your furnace might be having a low flame signal. This can happen even when your furnace is working like it should. It indicates the flame sensing rod could be dirty or in the wrong spot on the burner. Contact us at 805-242-9638 for support.

Here are some of the most routine problems for Lennox furnaces.
