While your Lennox® heating system can’t speak to you, it has a method to get your attention when there’s a furnace error.
Its control board has two LED lights that can show a fault code. Subject to the malfunction, your heater could display continuous or flashing lights.

What Does the Flickering Light on My Furnace Mean?
Your furnace depends on lights to flash code when it is malfunctioning. It also engages these lights to relay it’s heating like it should.
Correct operation involves:
- Simultaneous slow flash—heating system running like it should.
- Concurrent fast flash—heating system is beginning to call for heat.
If you realize that a solitary light blinking slowly and the other going on and off quickly, your furnace could be having a low flame signal. This can happen even when your heating system is operating correctly. It indicates the flame sensing rod might need to be cleaned or in the wrong location on the burner. Call us at 219-292-0956 for help.
Here are some of the most routine faults for Lennox heating systems.
Heating System Refuses to Turn On
Here are a few of the light arrangements you may notice when your heat won’t turn on or keep heating. The bulk of these problems need to be repaired by an expert, such as one from Struven Heating & Cooling.
- All LED lights aren’t lit. This means your HVAC system might not have power. Look at the breaker box to ensure the heater fuse hasn’t triggered. You should reset the fuse if it is in the “off” position. If it immediately flips after you reset it, don’t touch the breaker and call us at 219-292-0956.
- One light is stable and the other is flashing slowly. This shows the flame rollout switch is likely open. The part is a critical safety guard that helps in stopping fires and carbon monoxide. You shouldn’t attempt to repair this problem without professional help.
- A single light is blinking quickly and the other is blinking slowly. This likely signifies power polarity has been reversed. Your heating system might have a wiring error that calls for specialized aid from Struven Heating & Cooling.
- Both lights are flickering slowly. This indicates your furnace’s blower motor likely isn’t operating. This piece sends heated air from the heater into your home. We can aid in determining what’s wrong with this piece.
- A single light is flashing slowly and the other is blinking fast. This signifies your heater could have insufficient voltage or a short circuit. Call our experts at 219-292-0956 for assistance.
- One light is blinking on, on, off while the other blinks on, off, on. This signifies there could be trouble with your heating system’s control board or wiring. Struven Heating & Cooling can find the problem and repair it.
- The duo of lights show every other slow blinks. This means your heater possibly has a flame problem. There might be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 219-292-0956 for support.
- An individual light blinks slowly while the other remains continuous. This usually signifies your HVAC system’s limit switch is not working. The switch stops your heater from overheating. Get in touch with the pros at Struven Heating & Cooling for assistance.
Heater Blower Operates But No Warm Air
