While your Lennox® heating system cannot speak to you, it possesses a procedure to communicate a furnace error.

Its control panel has two LED lights that can share a fault code. Subject to the fault, your heating system could show solid or flashing lights.

What Does the Blinking Light on My Heating System Mean?

Your heating system depends on lights to flash code when it requires repairs. It also engages this setup to let you know it’s heating correctly.

Normal heating involves:

  • Simultaneous slow flash—heating system operating properly.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you notice a single light going on and off slowly and the other flashing fast, your heating system might be experiencing a low flame signal. This can happen even when your heating system is running like it should. It means the flame sensing rod may be dirty or in the wrong location on the burner. Contact us at 952-373-0377 for help.

Here are some of the most routine faults for Lennox HVAC systems.

Heater Refuses to Turn On

Here are many of the light sequences you may see when your heating system will not or keep running. Most of these issues have to be handled by a specialist, such as one from Gopher Heating and Air Conditioning.

  1. Both LED lights are off. This indicates your HVAC system might not have electricity. Go to the breaker box to confirm the furnace fuse is not tripped. Attempt to reset the fuse if it’s in the “off” area. If it instantly turns off after you reset it, don’t try to reset it again and get in touch with us us at 952-373-0377.
  2. A single light is stable and the other is flickering slowly. This implies the flame rollout switch is possibly not working right. The component is an essential safety tool that assists in avoiding fires and carbon monoxide. You shouldn’t try to repair this issue yourself.
  3. One light is flickering fast and the other is flickering slowly. This typically signifies power polarity has been inverted. Your heating system could have a wiring error that calls for specialized support from Gopher Heating and Air Conditioning.
  4. All lights are flickering slowly. This signifies your heating system’s blower motor probably isn’t running. This piece moves hot air from the HVAC system into your home. We can assist in determining what’s causing an issue with this component.
  5. A single light is flickering slowly and the other is blinking rapidly. This means your HVAC system could have low voltage or a short circuit. Call our technicians at 952-373-0377 for support.
  6. One light is blinking on, on, off while the other blinks on, off, on. This signifies there could be an issue with your heating system’s control board or wiring. Gopher Heating and Air Conditioning can locate the error and take care of it.
  7. Both lights show every other slow flickers. This signifies your heating system likely has a flame issue. There could be an issue with its gas supply, gas valve or ignitor control. Call us at 952-373-0377 for help.
  8. A single light blinks slowly while the other is solid. This usually means your HVAC equipment’s limit switch is experiencing an error. The switch stops your HVAC system from overheating. Get in touch with the experts at Gopher Heating and Air Conditioning for assistance.

Heater Blower Operates But No Warm Air

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