What Does the Blinking Light on My Furnace Mean?

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

Correct heating involves:

  • Simultaneous slow flash—furnace running like it should.
  • Concurrent fast flash—furnace is initiating the call for heat.

If you realize that a single light going on and off slowly and the other flashing fast, your heating system may be having a low flame signal. This can happen even when your heating system is heating properly. It signifies the flame sensing rod could need to be cleaned or in the wrong spot on the burner. Call us at 414-208-9000 for support.

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

Heater Will Not Kick On

Here are many of the light arrangements you could observe when your heating system won’t turn on or keep operating. The bulk of these problems must be taken care of by a specialist, such as one from Done Right Air.

  1. Both LED lights are off. This signifies your heating system might not have electricity. Go to the breaker box to confirm the heater fuse isn’t flipped. You should reset the fuse if it is in the “off” spot. If it promptly turns off after you reset it, don’t touch the breaker and get in touch with us us at 414-208-9000.
  2. One light is continuous and the other is flashing slowly. This signifies the flame rollout switch is possibly open. The component is a critical safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t attempt to fix this malfunction on your own.
  3. A single light is flickering fast and the other is flashing slowly. This likely indicates power polarity has been inverted. Your heater might have a wiring fault that needs specialized support from Done Right Air.
  4. The duo of lights are blinking slowly. This means your heating system’s blower motor possibly isn’t operating. This part circulates hot air from the furnace into your home. We can help in determining what’s causing an issue with this part.
  5. One light is flickering slowly and the other is flashing quickly. This means your heating system might have not enough voltage or a short circuit. Contact our specialists at 414-208-9000 for assistance.
  6. One light is flashing on, on, off while the other blinks on, off, on. This indicates there could be an issue with your HVAC system’s motherboard or wiring. Done Right Air can determine the error and handle it.
  7. The duo of lights are using every other slow blinks. This means your heater possibly has a flame issue. There could be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 414-208-9000 for support.
  8. A single light blinks slowly while the other is steady. This typically indicates your HVAC equipment’s limit switch is experiencing an error. The switch prevents your heating system from becoming too warm. Get in touch with the pros at Done Right Air for help.
