While your Lennox® HVAC equipment cannot speak to you, it possesses a way to get your attention when there’s a furnace error.

Its control board has two LED lights that can show a fault code. Subject to the failure, your heating system could display continuous or flashing lights.

Though there are various simple heating adjustments you can finish yourself, most tasks are best taken care of by HVAC technicians. When your heater will not kick on or provide heated air, reach out to Air Temperature Control at 478-202-3170 for professional furnace repair in Macon.

Our experts will quickly determine and take care of the problem, even if you don’t own a Lennox heating system. We can service all types or configuration—and get the heat returned to your house without delay.

What Does the Flashing Light on My Heating System Mean?

Your heater uses lights to flash code when it isn’t working right. It also uses this system to tell you it’s working properly.

Regular function consists of:

  • Concurrent slow flash—heater running properly.
  • Simultaneous fast flash—heater is initiating the call for heat.

If you realize that a solitary light blinking slowly and the other flashing rapidly, your heating system might be experiencing a low flame signal. This can take place even when your furnace is running correctly. It means the flame sensing rod could have buildup or in the incorrect area on the burner. Call us at 478-202-3170 for help.

Here are a few other of the most common faults for Lennox heaters.

Furnace Will Not Start

Here are some of the light arrangements you may observe when your heating system won’t turn on or keep heating. Most of these errors must be fixed by a professional, like one from Air Temperature Control.

  1. The duo of LED lights aren’t lit. This means your heater might not have electricity. Go to the breaker box to make sure the heating system fuse hasn’t flipped. Try resetting the fuse if it is in the “off” spot. If it rapidly turns off after a subsequent reset, don’t touch the breaker and call us at 478-202-3170.
  2. A single light is stable and the other is blinking slowly. This signifies the flame rollout switch is possibly not working right. The switch is an essential safety guard that assists in avoiding fires and carbon monoxide. You shouldn’t try to handle this issue on your own.
  3. A single light is blinking fast and the other is blinking slowly. This likely signifies power polarity has been transposed. Your furnace may have a wiring error that needs expert help from Air Temperature Control.
  4. The pair of lights are flickering slowly. This signifies your heating system’s blower motor likely isn’t running. This component distributes hot air from the heater into your residence. We can aid in pinpointing what’s causing a problem with this piece.
  5. A single light is flickering slowly and the other is blinking fast. This signifies your heating system may have low voltage or a short circuit. Contact our technicians at 478-202-3170 for help.
  6. One light is blinking on, on, off while the other flashes on, off, on. This indicates there might be a fault with your heating system’s control board or wiring. Air Temperature Control can locate the fault and repair it.
  7. The pair of lights display alternate slow flashes. This signifies your HVAC equipment may have a flame error. There could be a problem with its gas supply, gas valve or ignitor control. Call us at 478-202-3170 for assistance.
