While your Lennox® heating system can’t speak to you, it has a procedure to get your attention when there’s a furnace error.
Its control panel has double LED lights that can display a fault code. Subject to the malfunction, your furnace might display continuous or flashing lights.

Our specialists will quickly discover and fix the issue, even if you don’t own a Lennox heater. We can repair all kinds or makes—and get the heat reintroduced to your house fast.
What Does the Flashing Light on My Heater Mean?
Your furnace depends on lights to flash code when it requires repairs. It also engages this setup to tell you it’s heating properly.
Normal operation consists of:
- Simultaneous slow flash—heater working properly.
- Simultaneous fast flash—heater is beginning to call for heat.
If you realize that a single light going on and off slowly and the other going on and off rapidly, your furnace might be having a low flame signal. This can take place even when your furnace is operating correctly. It indicates the flame sensing rod may be dirty or in the bad area on the burner. Contact us at 507-387-6596 for support.
Here are several other of the most typical errors for Lennox heaters.
Heating System Refuses to Kick On
Here are many of the light patterns you could observe when your heating system refuses to or keep operating. Most of these problems have to be repaired by an expert, like one from Northern Comfort Inc.
- The duo of LED lights are off. This signifies your heater might not have power. Examine the breaker box to make sure the heating system fuse is not tripped. Try resetting the fuse if it’s in the “off” area. If it rapidly turns off after you reset it, don’t touch the breaker and contact us at 507-387-6596.
- An individual light is continuous and the other is flickering slowly. This shows the flame rollout switch is likely not working right. The component is a critical safety tool that helps in stopping fires and carbon monoxide. You shouldn’t try to repair this problem yourself.
- An individual light is flickering rapidly and the other is flashing slowly. This often signifies power polarity has been inverted. Your heater may have a wiring error that requires professional aid from Northern Comfort Inc.
- All lights are flashing slowly. This signifies your heater’s blower motor probably isn’t operating. This piece sends warm air from the heating system into your house. We can help in determining what’s causing an issue with this piece.
- A single light is flickering slowly and the other is blinking quickly. This means your HVAC system may have not enough voltage or a short circuit. Reach out to our technicians at 507-387-6596 for assistance.
- One light is blinking on, on, off while the other blinks on, off, on. This indicates there may be a fault with your HVAC system’s motherboard or wiring. Northern Comfort Inc can determine the problem and repair it.
- The pair of lights show every other slow blinks. This means your heater may have a flame error. There might be an issue with its gas supply, gas valve or ignitor control. Contact us at 507-387-6596 for help.
- A single light blinks slowly while the other remains solid. This often means your heater’s limit switch is not working. The switch keeps your heater from getting too hot. Call the specialists at Northern Comfort Inc for assistance.
Heater Blower Runs But No Warm Air
Here’s what may be broken when you notice your heating system’s blower fan working, but you aren’t gaining any warm air.
- The pair of lights are giving alternate fast flashes. This indicates your furnace ignitor might not be working. This component kindles gas in your heater to create warmth and should be fixed by an expert from Northern Comfort Inc.
