While your Lennox® furnace cannot speak to you, it has a way to communicate a furnace error.

Its control board has a set of LED lights that can share a fault code. Subject to the fault, your furnace may show continuous or flashing lights.

Our specialists will speedily determine and take care of the problem, even if you don’t use a Lennox heater. We can repair any types or models—and get the heat returned to your home fast.

What Does the Flickering Light on My Heating System Mean?

Your furnace depends on lights to flash code when it is malfunctioning. It also uses this setup to let you know it’s heating like it should.

Regular operation includes:

  • Simultaneous slow flash—heating system working properly.
  • Concurrent fast flash—heating system is beginning to call for heat.

If you realize that a lone light going on and off slowly and the other blinking rapidly, your furnace may be experiencing a low flame signal. This can take place even when your furnace is operating correctly. It means the flame sensing rod may have buildup or in the bad area on the burner. Reach out to us at 541-238-2797 for help.

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