While your Lennox® heater isn’t able to speak to you, it has a process to tell you about a furnace error.
Its control panel has a set of LED lights that can share a fault code. Subject to the problem, your furnace could display continuous or flashing lights.

What Does the Flashing Light on My Heating System Mean?
Your heater relies on lights to flash code when it isn’t working right. It also uses this system to tell you it’s working properly.
Correct function includes:
- Concurrent slow flash—furnace operating like it should.
- Both lights flash fast—heater is initiating the call for heat.
If you notice a solitary light going on and off slowly and the other going on and off quickly, your heating system could have a low flame signal. This can take place even when your heating system is running correctly. It indicates the flame sensing rod may be dirty or in the incorrect area on the burner. Call us at 360-255-5857 for assistance.
