What Does the Blinking Light on My Furnace Mean?

Your heating system relies on lights to flash code when it isn’t working right. It also engages these lights to relay it’s working properly.

Regular operation consists of:

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

If you see a lone light flashing slowly and the other flashing rapidly, your furnace might have a low flame signal. This can take place even when your furnace is running correctly. It indicates the flame sensing rod might need to be cleaned or in the bad location on the burner. Contact us at 256-801-4701 for assistance.

Here are some of the most typical issues for Lennox furnaces.

Heating System Will Not Kick On

Here are a few of the light arrangements you could notice when your furnace will not or keep operating. The bulk of these errors have to be repaired by a specialist, such as one from All Weather Heating & Air Conditioning Inc.

  1. The pair of LED lights are off. This means your HVAC system might not be receiving power. Find the breaker box to ensure the heating system fuse has not triggered. Try resetting the fuse if it is in the “off” area. If it rapidly trips after a subsequent reset, don’t touch the breaker and contact us at 256-801-4701.
  2. A single light is continuous and the other is flashing slowly. This shows the flame rollout switch is likely malfunctioning. The part is an essential safety guard that aids in avoiding fires and carbon monoxide. You shouldn’t seek to repair this problem yourself.
  3. A single light is flickering fast and the other is flashing slowly. This often indicates power polarity has been reversed. Your furnace may have a wiring fault that needs professional support from All Weather Heating & Air Conditioning Inc.
  4. The duo of lights are blinking slowly. This means your heater’s blower motor probably isn’t working. This component sends heated air from the HVAC system into your house. We can aid in figuring out what’s causing an issue with this component.
  5. A single light is flashing slowly and the other is flickering rapidly. This means your HVAC system could have not enough voltage or a short circuit. Contact our experts at 256-801-4701 for help.
  6. One light is flickering on, on, off while the other flickers on, off, on. This means there may be an issue with your HVAC system’s control panel or wiring. All Weather Heating & Air Conditioning Inc can find the problem and handle it.
  7. The duo of lights are using alternate slow blinks. This signifies your heater may have a flame problem. There may be trouble with its gas supply, gas valve or ignitor control. Call us at 256-801-4701 for help.
  8. A single light flickers slowly while the other stays steady. This usually signifies your HVAC equipment’s limit switch is not working. The switch stops your HVAC system from overheating. Reach out to the professionals at All Weather Heating & Air Conditioning Inc for support.
