While your Lennox® furnace isn’t able to chat with you, it does have a procedure to tell you about a furnace error.
Its motherboard has double LED lights that can display a fault code. Depending on the fault, your furnace could display steady or flashing lights.

What Does the Blinking Light on My Heater Mean?
Your furnace uses lights to flash code when it is malfunctioning. It also works this system to tell you it’s running properly.
Correct operation consists of:
- Simultaneous slow flash—furnace operating properly.
- Simultaneous fast flash—heater is beginning to call for heat.
If you see one light blinking slowly and the other going on and off quickly, your heater might be experiencing a low flame signal. This can take place even when your heater is heating correctly. It means the flame sensing rod may have build-up or in the incorrect location on the burner. Contact us at 979-335-4262 for support.
Here are a few other of the most routine errors for Lennox furnaces.
Furnace Won’t Kick On
Here are a few of the light sequences you could notice when your heating system refuses to or stay on. The majority of these errors must be taken care of by an expert, for instance from E.B. Air, LLC.
- All LED lights are off. This means your furnace might not be receiving power. Find the breaker box to confirm the heater fuse hasn’t tripped. Try resetting the fuse if it’s in the “off” spot. If it rapidly turns off after a subsequent reset, don’t touch the breaker and get in touch with us us at 979-335-4262.
- An individual light is continuous and the other is flickering slowly. This shows the flame rollout switch is possibly not working right. The part is a critical safety tool that helps in preventing fires and carbon monoxide. You shouldn’t attempt to handle this malfunction on your own.
- An individual light is flickering rapidly and the other is blinking slowly. This often signifies power polarity has been transposed. Your heater might have a wiring issue that requires expert help from E.B. Air, LLC.
- Both lights are flickering slowly. This indicates your furnace’s blower motor probably isn’t running. This part moves hot air from the heater into your home. We can assist in figuring out what’s causing an issue with this part.
- A single light is blinking slowly and the other is blinking quickly. This signifies your heater might have not enough voltage or a short circuit. Call our specialists at 979-335-4262 for help.
- One light is flickering on, on and off while the other flashes on, off, on. This indicates there might be an issue with your heating system’s control panel or wiring. E.B. Air, LLC can pinpoint the fault and fix it.
- The pair of lights show alternating slow flickers. This signifies your heater may have a flame error. There may be trouble with its gas supply, gas valve or ignitor control. Call us at 979-335-4262 for support.
- An individual light blinks slowly while the other is steady. This typically signifies your heater’s limit switch is malfunctioning. The switch prevents your HVAC equipment from overheating. Reach out to the professionals at E.B. Air, LLC for help.
Heater Blower Works But No Warmth
Here’s what may be wrong when you hear your heating equipment’s blower fan running, but you aren’t receiving any warm air.
- Both lights display alternating fast flickers. This signifies your furnace ignitor might be broken. This component ignites fuel in your HVAC equipment to create warmth and should be serviced by a specialist from E.B. Air, LLC.
