While your Lennox® furnace can’t chat with you, it has a procedure to communicate a furnace error.

Its control board has two LED lights that can share a fault code. Based on the failure, your heater might use steady or flashing lights.

Although there are some simple furnace adjustments you can take care of on your own, the majority of tasks are best left to HVAC technicians. When your furnace refuses to kick on or give heated air, contact AW Heating & Air Conditioning at 402-438-7992 for expert furnace repair in Lincoln.

Our technicians will swiftly identify and repair the breakdown, even if you don’t use a Lennox heater. We can service whichever kinds or configuration—and get the warmth returned to your home without delay.

What Does the Blinking Light on My Heating System Mean?

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

Correct operation includes:

  • Concurrent slow flash—furnace working properly.
  • Both lights flash fast—heater is beginning to call for heat.

If you see a single light flashing slowly and the other flashing quickly, your furnace could be having a low flame signal. This can take place even when your heating system is operating like it should. It indicates the flame sensing rod might need to be cleaned or in the wrong area on the burner. Reach out to us at 402-438-7992 for assistance.

Here are some of the most common errors for Lennox heating systems.

Furnace Won’t Start

Here are some of the light arrangements you might observe when your heat will not or keep heating. Most of these issues need to be handled by a specialist, for instance from AW Heating & Air Conditioning.

  1. Both LED lights are off. This means your heating system might not be receiving power. Examine the breaker box to make sure the heating system fuse hasn’t flipped. You should reset the fuse if it is in the “off” spot. If it promptly trips after you reset it, don’t try to reset it again and get in touch with us us at 402-438-7992.
  2. One light is continuous and the other is blinking slowly. This shows the flame rollout switch is may be malfunctioning. The component is a critical safety guard that aids in avoiding fires and carbon monoxide. You shouldn’t attempt to take care of this malfunction without professional help.
  3. One light is flickering fast and the other is flashing slowly. This often means power polarity has been reversed. Your furnace may have a wiring fault that calls for specialized assistance from AW Heating & Air Conditioning.
  4. The duo of lights are flickering slowly. This means your heating system’s blower motor likely isn’t working. This component distributes heated air from the heating system into your home. We can help in figuring out what’s causing an issue with this part.
  5. An individual light is flickering slowly and the other is flashing quickly. This means your HVAC system may have not enough voltage or a short circuit. Contact our technicians at 402-438-7992 for support.
  6. One light is blinking on, on, off while the other blinks on, off, on. This indicates there could be trouble with your HVAC system’s control board or wiring. AW Heating & Air Conditioning can locate the problem and take care of it.
  7. The duo of lights display alternate slow flashes. This means your heater likely has a flame failure. There may be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 402-438-7992 for help.
  8. An individual light blinks slowly while the other is steady. This usually indicates your heater’s limit switch is not working. The switch prevents your heater from getting too hot. Reach out to the pros at AW Heating & Air Conditioning for help.

Heating System Blower Operates But No Warm Air

Here’s what could be wrong when you notice your heater’s blower fan running, but you aren’t receiving any warmth.

  • The pair of lights display alternate quick flickers. This signifies your furnace ignitor could be broken. This piece kindles gas in your heater to make heat and should be serviced by a specialist from AW Heating & Air Conditioning.
