While your Lennox® furnace cannot chat with you, it has a procedure to communicate a furnace error.
Its control panel has double LED lights that can share a fault code. Depending on the malfunction, your heating system may display solid or flashing lights.

Our experts will speedily identify and fix the problem, even if you don’t have a Lennox heating system. We can repair all types or models—and get the comfort reintroduced to your house without delay.
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 heating like it should.
Correct heating involves:
- Concurrent slow flash—furnace operating properly.
- Simultaneous fast flash—heater is starting to call for heat.
If you notice a single light blinking slowly and the other blinking quickly, your furnace might have a low flame signal. This can occur even when your heater is heating properly. It means the flame sensing rod could have buildup or in the bad spot on the burner. Call us at 208-561-1226 for help.
Here are a few other of the most routine faults for Lennox HVAC systems.
Furnace Won’t Start
Here are some of the light arrangements you might see when your furnace will not or keep operating. The majority of these problems must be fixed by a specialist, like one from Alpine Summit Heating & Cooling.
- The duo of LED lights are extinguished. This signifies your HVAC system might not have electricity. Find the breaker box to confirm the furnace fuse has not triggered.

- An individual light is continuous and the other is flashing slowly. This implies the flame rollout switch is possibly not working right. The component is a critical safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t seek to take care of this problem without professional help.
- An individual light is flickering fast and the other is blinking slowly. This likely signifies power polarity has been inverted. Your heater could have a wiring problem that calls for specialized help from Alpine Summit Heating & Cooling.
