What Does the Flickering Light on My Heating System Mean?

Your heater relies on lights to flash code when it is malfunctioning. It also works these lights to relay it’s operating properly.

Correct operation includes:

  • Simultaneous slow flash—furnace working properly.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you notice a single light flashing slowly and the other going on and off quickly, your furnace could have a low flame signal. This can take place even when your heater is working properly. It signifies the flame sensing rod could need to be cleaned or in the incorrect area on the burner. Call us at 405-494-7444 for support.

Here are some of the most typical faults for Lennox heaters.

Furnace Won’t Start

Here are a few of the light sequences you could see when your heat will not or keep operating. The bulk of these issues must be handled by a professional, such as one from Comfort Concepts Heating & Air Conditioning.

  1. Both LED lights are extinguished. This signifies your HVAC system might not be receiving power. Look at the breaker box to ensure the heating system fuse has not triggered. Attempt to reset the fuse if it’s in the “off” position. If it promptly trips after you reset it, don’t try to reset it again and contact us at 405-494-7444.
  2. One light is stable and the other is flashing slowly. This signifies the flame rollout switch is possibly malfunctioning. The switch is a critical safety device that assists in stopping fires and carbon monoxide. You shouldn’t seek to fix this fault on your own.
  3. An individual light is flickering quickly and the other is flashing slowly. This likely means power polarity has been reversed. Your heater may have a wiring error that calls for expert assistance from Comfort Concepts Heating & Air Conditioning.
  4. All lights are flashing slowly. This means your heating system’s blower motor probably isn’t operating. This component sends hot air from the heating system into your rooms. We can assist in figuring out what’s wrong with this component.
  5. One light is blinking slowly and the other is blinking quickly. This signifies your heater could have insufficient voltage or a short circuit. Call our technicians at 405-494-7444 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 HVAC system’s control board or wiring. Comfort Concepts Heating & Air Conditioning can determine the fault and repair it.
  7. The pair of lights show alternate slow blinks. This signifies your HVAC equipment may have a flame error. There may be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 405-494-7444 for support.
  8. A single light flashes slowly while the other remains solid. This usually means your heating system’s limit switch is experiencing an error. The switch keeps your heater from overheating. Reach out to the professionals at Comfort Concepts Heating & Air Conditioning for assistance.

Heater Blower Works But No Warmth

Here’s what might be at fault when you hear your heating system’s blower fan working, but you aren’t receiving any warm air.

  • The pair of lights are giving every other fast flashes. This indicates your furnace ignitor could be broken. This component ignites fuel in your HVAC equipment to create warmth and should be fixed by a specialist from Comfort Concepts Heating & Air Conditioning.
