While your Lennox® heating system cannot chat with you, it does have a way to get your attention when there’s a furnace error.

Its control board has twin LED lights that can show a fault code. Depending on the failure, your heating system might display continuous or flashing lights.

What Does the Flashing Light on My Heating System Mean?

Your furnace uses lights to flash code when it is malfunctioning. It also works these lights to let you know it’s operating properly.

Normal function involves:

  • Simultaneous slow flash—heating system operating like it should.
  • Both lights flash fast—heater is beginning to call for heat.

If you notice a lone light going on and off slowly and the other going on and off quickly, your heating system may be experiencing a low flame signal. This can occur even when your furnace is running like it should. It indicates the flame sensing rod could need to be cleaned or in the wrong spot on the burner. Call us at 478-200-5689 for assistance.

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

Furnace Won’t Kick On

Here are a few of the light sequences you could observe when your heating system won’t turn on or keep operating. Most of these issues must be taken care of by a professional, for instance from Air Concepts of Middle Georgia.

  1. Both LED lights aren’t lit. This means your heater might not have power. Go to the breaker box to confirm the heater fuse hasn’t triggered. Attempt to reset the fuse if it’s in the “off” area. If it promptly turns off after you reset it, don’t touch the breaker and contact us at 478-200-5689.
  2. One light is unchanging and the other is blinking slowly. This shows the flame rollout switch is likely open. The switch is a critical safety guard that helps in preventing fires and carbon monoxide. You shouldn’t attempt to handle this fault yourself.
  3. One light is blinking fast 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 support from Air Concepts of Middle Georgia.
  4. All lights are flashing slowly. This indicates your heater’s blower motor likely isn’t operating. This part sends warm air from the heater into your rooms. We can help in pinpointing what’s wrong with this part.
  5. An individual light is blinking slowly and the other is blinking quickly. This signifies your heater could have low voltage or a short circuit. Contact our experts at 478-200-5689 for support.
  6. One light is blinking on, on, off while the other flashes on, off, on. This signifies there may be an issue with your heating system’s motherboard or wiring. Air Concepts of Middle Georgia can pinpoint the issue and take care of it.
  7. The pair of lights are using every other slow blinks. This means your heating system possibly has a flame error. There could be a problem with its gas supply, gas valve or ignitor control. Call us at 478-200-5689 for help.
  8. An individual light flashes slowly while the other stays continuous. This often means your heater’s limit switch is malfunctioning. The switch prevents your heater from becoming too warm. Call the pros at Air Concepts of Middle Georgia for assistance.

Heating System Blower Runs But No Warmth
