While your Lennox® HVAC equipment cannot speak to you, it does have a method to communicate a furnace error.
Its control board has double LED lights that can display a fault code. Subject to the failure, your furnace might use continuous or flashing lights.

Our technicians will speedily identify and repair the problem, even if you don’t have a Lennox heater. We can service whichever types or configuration—and get the heat returned to your residence fast.
What Does the Flickering Light on My Heating System Mean?
Your heater uses lights to flash code when it requires repairs. It also engages these lights to relay it’s operating correctly.
Correct function involves:
- Simultaneous slow flash—heating system running properly.
- Both lights flash fast—heater is starting to call for heat.
If you realize that a single light blinking slowly and the other going on and off fast, your heating system may be experiencing a low flame signal. This can happen even when your furnace is running properly. It signifies the flame sensing rod may be dirty or in the incorrect location on the burner. Call us at 478-202-3170 for assistance.
Here are a few other of the most typical errors for Lennox furnaces.
