While your Lennox® heater isn’t able to speak to you, it possesses a way to communicate a furnace error.
Its control board has a set of LED lights that can display a fault code. Based on the issue, your furnace could display solid or flashing lights.

What Does the Flickering Light on My Furnace Mean?
Your furnace uses lights to flash code when it is malfunctioning. It also works this system to relay it’s working like it should.
Normal function includes:
- Simultaneous slow flash—heating system operating correctly.
- Both lights flash fast—heating system is initiating the call for heat.
If you realize that a lone light blinking slowly and the other blinking quickly, your furnace could be experiencing a low flame signal. This can occur even when your heater is working like it should. It indicates the flame sensing rod could be dirty or in the bad location on the burner. Call us at 740-474-5940 for help.
Here are some of the most typical issues for Lennox furnaces.
