What Does the Flickering Light on My Furnace Mean?

Your furnace depends on lights to flash code when it isn’t working right. It also engages this system to relay it’s operating properly.

Regular heating includes:

  • Concurrent slow flash—furnace running correctly.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you realize that a lone light going on and off slowly and the other going on and off fast, your furnace may be experiencing a low flame signal. This can take place even when your furnace is heating like it should. It means the flame sensing rod may have buildup or in the bad area on the burner. Call us at 203-772-8319 for support.
