While your Lennox® HVAC equipment cannot speak to you, it does have a method to get your attention when there’s a furnace error.

Its control panel has two LED lights that can share a fault code. Based on the issue, your furnace may use continuous or flashing lights.

Our experts will rapidly identify and take care of the malfunction, even if you don’t own a Lennox heating system. We can service whichever types or models—and get the warmth reintroduced to your house quickly.

What Does the Flickering Light on My Heating System Mean?

Your heater depends on lights to flash code when it is malfunctioning. It also works this system to relay it’s working correctly.

Normal heating involves:

  • Simultaneous slow flash—furnace heating like it should.
  • Simultaneous fast flash—heating system is beginning to call for heat.

If you see a single light blinking slowly and the other flashing rapidly, your heating system may be experiencing a low flame signal. This can happen even when your furnace is heating like it should. It means the flame sensing rod may have buildup or in the bad area on the burner. Call us at 843-253-4874 for assistance.

Here are several other of the most typical problems for Lennox heaters.

Furnace Won’t Start

Here are some of the light sequences you may see when your heating system won’t turn on or keep running. The majority of these issues need to be handled by a professional, such as one from Polar Air & Mechanical.

  1. Both LED lights are off. This means your heating system might not have power. Go to the breaker box to confirm the heating system fuse is not tripped. You should reset the fuse if it is in the “off” position. If it immediately trips after a subsequent reset, don’t try to reset it again and get in touch with us us at 843-253-4874.
  2. An individual light is unchanging and the other is flashing slowly. This implies the flame rollout switch is likely malfunctioning. The switch is a critical safety mechanism that assists in stopping fires and carbon monoxide. You shouldn’t attempt to fix this issue on your own.
  3. One light is flickering quickly and the other is flashing slowly. This often signifies power polarity has been transposed. Your furnace might have a wiring fault that calls for expert aid from Polar Air & Mechanical.
  4. All lights are blinking slowly. This signifies your furnace’s blower motor likely isn’t working. This part distributes warm air from the heater into your rooms. We can help in determining what’s wrong with this part.
  5. One light is blinking slowly and the other is blinking fast. This signifies your heating system could have low voltage or a short circuit. Get in touch with our technicians at 843-253-4874 for help.
  6. One light is flashing on, on, off while the other flickers on, off, on. This indicates there may be trouble with your HVAC system’s motherboard or wiring. Polar Air & Mechanical can locate the error and take care of it.
  7. The duo of lights display every other slow blinks. This signifies your HVAC system likely has a flame problem. There could be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 843-253-4874 for support.
  8. An individual light flashes slowly while the other remains steady. This usually means your heating system’s limit switch is not working. The switch keeps your heater from becoming too warm. Reach out to the experts at Polar Air & Mechanical for help.

Heater Blower Operates But No Heat

Here’s what might be broken when you notice your heating system’s blower fan working, but you aren’t getting any warm air.

  • Both lights display alternate quick blinks. This signifies your furnace ignitor may not be in working order. This piece ignites energy in your heating system to make warmth and should be repaired by a technician from Polar Air & Mechanical.
