While your Lennox® HVAC equipment cannot speak to you, it does have a method to communicate a furnace error.

Its control board has double LED lights that can display a fault code. Subject to the failure, your furnace might use continuous or flashing lights.

What Does the Flickering Light on My Heating System Mean?

Your heater uses lights to flash code when it requires repairs. It also engages these lights to relay it’s operating correctly.

Correct function involves:

  • Simultaneous slow flash—heating system running properly.
  • Both lights flash fast—heater is starting to call for heat.

If you realize that a single light blinking slowly and the other going on and off fast, your heating system may be experiencing a low flame signal. This can happen even when your furnace is running properly. It signifies the flame sensing rod may be dirty or in the incorrect location on the burner. Call us at 478-202-3170 for assistance.

Here are a few other of the most typical errors for Lennox furnaces.

Furnace Won’t Turn On

Here are a few of the light arrangements you may see when your heater will not or keep heating. Most of these problems must be repaired by a technician, like one from Air Temperature Control.

  1. Both LED lights aren’t lit. This means your heating system might not have power. Go to the breaker box to confirm the heating system fuse is not tripped. Try resetting the fuse if it’s in the “off” position. If it promptly trips after a subsequent reset, don’t touch the breaker and get in touch with us us at 478-202-3170.
  2. An individual light is unchanging and the other is flickering slowly. This implies the flame rollout switch is may be malfunctioning. The switch is a critical safety tool that helps in avoiding fires and carbon monoxide. You shouldn’t try to take care of this issue without professional help.
  3. An individual light is blinking quickly and the other is flickering slowly. This typically means power polarity has been reversed. Your heating system might have a wiring fault that requires expert help from Air Temperature Control.
  4. Both lights are flashing slowly. This means your heating system’s blower motor probably isn’t working. This part sends warm air from the HVAC system into your residence. We can assist in pinpointing what’s causing an issue with this component.
  5. An individual light is flashing slowly and the other is blinking rapidly. This signifies your heater might have low voltage or a short circuit. Call our specialists at 478-202-3170 for help.
  6. One light is flickering on, on, off while the other flickers on, off, on. This signifies there might be a fault with your heater’s control panel or wiring. Air Temperature Control can determine the error and repair it.
  7. The duo of lights show every other slow blinks. This signifies your HVAC equipment likely has a flame failure. There may be an issue with its gas supply, gas valve or ignitor control. Contact us at 478-202-3170 for assistance.
  8. A single light flickers slowly while the other remains steady. This typically indicates your HVAC equipment’s limit switch is malfunctioning. The switch prevents your HVAC equipment from becoming too warm. Reach out to the specialists at Air Temperature Control for help.

Heating System Blower Works But No Heat

Here’s what might be broken when you notice your heater’s blower fan on, but you aren’t getting any heated air.

  • Both lights are giving alternate fast flickers. This means your furnace ignitor could be broken. This part ignites gas in your heating system to produce heat and should be fixed by an expert from Air Temperature Control.
