While your Lennox® heater cannot speak to you, it possesses a process to communicate a furnace error.
Its motherboard has a set of LED lights that can share a fault code. Subject to the issue, your heater might show continuous or flashing lights.

What Does the Blinking Light on My Furnace Mean?
Your heating system depends on lights to flash code when it needs to be repaired. It also uses this system to tell you it’s heating like it should.
Regular function involves:
- Simultaneous slow flash—heater operating properly.
- Simultaneous fast flash—furnace is starting to call for heat.
If you notice one light going on and off slowly and the other flashing quickly, your heating system might be having a low flame signal. This can take place even when your furnace is running like it should. It means the flame sensing rod may have build-up or in the incorrect area on the burner. Contact us at 614-450-1575 for assistance.
