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

Its control board has a set of LED lights that can show a fault code. Subject to the problem, your heating system may display solid or flashing lights.

What Does the Blinking Light on My Furnace Mean?

Your heating system uses lights to flash code when it isn’t working right. It also engages this system to tell you it’s working like it should.

Regular function includes:

  • Simultaneous slow flash—furnace running like it should.
  • Both lights flash fast—heater is beginning to call for heat.

If you see a solitary light blinking slowly and the other blinking quickly, your heating system may have a low flame signal. This can happen even when your furnace is running properly. It means the flame sensing rod may be dirty or in the incorrect area on the burner. Contact us at 928-432-6018 for support.

Here are a few other of the most typical issues for Lennox heaters.

Heater Won’t Turn On

Here are some of the light patterns you may notice when your heating system will not or keep operating. The majority of these errors must be handled by a technician, for instance from B&D Air Conditioning.

  1. The pair of LED lights are extinguished. This means your heating system might not have power. Look at the breaker box to make sure the furnace fuse has not flipped. Try resetting the fuse if it is in the “off” spot. If it immediately flips after a subsequent reset, don’t try to reset it again and contact us at 928-432-6018.
  2. An individual light is continuous and the other is flashing slowly. This shows the flame rollout switch is may be malfunctioning. The component is an essential safety guard that helps in avoiding fires and carbon monoxide. You shouldn’t seek to take care of this problem yourself.
  3. One light is flickering quickly and the other is flashing slowly. This typically signifies power polarity has been inverted. Your heating system may have a wiring fault that calls for specialized aid from B&D Air Conditioning.
  4. Both lights are blinking slowly. This means your furnace’s blower motor likely isn’t operating. This component sends hot air from the heating system into your house. We can help in determining what’s wrong with this component.

  8. An individual light flashes slowly while the other remains steady. This usually means your HVAC system’s limit switch is malfunctioning. The switch keeps your HVAC equipment from getting too hot. Reach out to the experts at B&D Air Conditioning for support.
