While your Lennox® heater cannot chat with you, it does have a procedure to communicate a furnace error.

Its motherboard has twin LED lights that can show a fault code. Based on the problem, your furnace could show solid or flashing lights.

What Does the Flickering Light on My Furnace Mean?

Your heater relies on lights to flash code when it is malfunctioning. It also works these lights to tell you it’s working properly.

Correct operation involves:

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

If you see a single light blinking slowly and the other flashing quickly, your heating system may be having a low flame signal. This can happen even when your heating system is operating properly. It means the flame sensing rod might be dirty or in the bad spot on the burner. Reach out to us at 302-231-1380 for help.

Here are a few other of the most typical faults for Lennox HVAC systems.
