While your Lennox® furnace can’t speak to you, it possesses a method to tell you about a furnace error.

Its control panel has a set of LED lights that can show a fault code. Based on the fault, your heater may show continuous or flashing lights.

Though there are certain elementary HVAC repairs you can finish without an expert, most tasks are best handled by HVAC technicians. When your furnace refuses to kick on or deliver heat, call Classic Air at 614-210-3041 for professional furnace repair in Columbus.

Our specialists will speedily identify and take care of the problem, even if you don’t own a Lennox heater. We can repair all kinds or makes—and get the warmth returned to your home without delay.

What Does the Flashing Light on My Furnace Mean?

Your furnace relies on lights to flash code when it is malfunctioning. It also engages this system to let you know it’s heating like it should.

Normal operation includes:

  • Concurrent slow flash—heater running correctly.
  • Concurrent fast flash—heater is beginning to call for heat.

If you see a lone light blinking slowly and the other blinking rapidly, your heating system could have a low flame signal. This can occur even when your heating system is heating like it should. It means the flame sensing rod may need to be cleaned or in the bad location on the burner. Reach out to us at 614-210-3041 for support.

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

Furnace Refuses to Turn On

Here are many of the light sequences you may observe when your heater refuses to or keep running. Most of these issues need to be handled by a specialist, for instance from Classic Air.

  1. Both LED lights are extinguished. This signifies your heating system might not be receiving power. Go to the breaker box to make sure the furnace fuse isn’t triggered. You should reset the fuse if it’s in the “off” position. If it rapidly trips after a subsequent reset, don’t try to reset it again and contact us at 614-210-3041.
  2. An individual light is stable and the other is flashing slowly. This signifies the flame rollout switch is possibly open. The component is an essential safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t seek to repair this fault without professional help.
  3. A single light is flickering quickly and the other is blinking slowly. This often means power polarity has been reversed. Your heater may have a wiring error that calls for specialized assistance from Classic Air.
  4. The pair of lights are flashing slowly. This means your heating system’s blower motor probably isn’t operating. This part sends warm air from the heater into your home. We can help in determining what’s causing a problem with this part.
  5. One light is blinking slowly and the other is blinking quickly. This signifies your HVAC system might have not enough voltage or a short circuit. Contact our technicians at 614-210-3041 for help.
  6. One light is flashing on, on, off while the other flickers on, off, on. This means there may be a malfunction with your heating system’s control board or wiring. Classic Air can pinpoint the issue and handle it.
  7. The pair of lights display every other slow blinks. This signifies your HVAC equipment may have a flame problem. There could be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 614-210-3041 for support.
  8. An individual light blinks slowly while the other is solid. This often indicates your HVAC equipment’s limit switch is malfunctioning. The switch keeps your HVAC equipment from getting too hot. Get in touch with the experts at Classic Air for support.

Heating System Blower Works But No Warmth

Here’s what could be broken when you hear your heating equipment’s blower fan running, but you aren’t gaining any warmth.

  • The duo of lights display alternate quick flashes. This signifies your furnace ignitor could be broken. This component lights gas in your HVAC equipment to create heat and should be serviced by a technician from Classic Air.
