While your Lennox® HVAC equipment cannot chat with you, it possesses a procedure to communicate a furnace error.

Its control panel has double LED lights that can show a fault code. Based on the problem, your heating system may show continuous or flashing lights.

While there are a few elementary HVAC repairs you can finish without an expert, the majority of services are best taken care of by HVAC technicians. When your heater won’t kick on or give warm air, call Home Comfort Heating & Air at 763-276-0617 for experienced furnace repair in Elk River.

Our technicians will quickly determine and handle the breakdown, even if you don’t use a Lennox heating system. We can service all kinds or makes—and get the comfort returned to your home quickly.

What Does the Flickering Light on My Heater Mean?

Your heater uses lights to flash code when it is malfunctioning. It also uses this system to let you know it’s heating properly.

Correct heating involves:

  • Simultaneous slow flash—furnace running like it should.
  • Simultaneous fast flash—heater is beginning to call for heat.

If you realize that a lone light going on and off slowly and the other blinking rapidly, your heating system might have a low flame signal. This can occur even when your heating system is heating like it should. It indicates the flame sensing rod might need to be cleaned or in the wrong area on the burner. Contact us at 763-276-0617 for help.

Here are a few other of the most common issues for Lennox furnaces.

Furnace Will Not Kick On

Here are many of the light arrangements you might notice when your heater refuses to or keep running. Most of these problems must be repaired by a professional, like one from Home Comfort Heating & Air.

  1. All LED lights are off. This signifies your heating system might not have electricity. Go to the breaker box to ensure the heater fuse isn’t tripped. Attempt to reset the fuse if it’s in the “off” position. If it instantly trips following a reset, don’t try to reset it again and contact us at 763-276-0617.
  2. An individual light is continuous and the other is flickering slowly. This shows the flame rollout switch is possibly not working right. The part is an essential safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t seek to fix this malfunction without professional help.
  3. An individual light is flashing rapidly and the other is flashing slowly. This likely indicates power polarity has been transposed. Your heating system could have a wiring fault that needs specialized help from Home Comfort Heating & Air.
  4. All lights are flashing slowly. This indicates your heater’s blower motor probably isn’t operating. This part distributes heated air from the HVAC system into your house. We can help in figuring out what’s wrong with this component.
  5. One light is flickering slowly and the other is blinking rapidly. This means your heating system might have not enough voltage or a short circuit. Reach out to our specialists at 763-276-0617 for support.
  6. One light is blinking on, on, off while the other blinks on, off, on. This means there may be trouble with your HVAC system’s motherboard or wiring. Home Comfort Heating & Air can locate the problem and repair it.
  7. The duo of lights are using every other slow blinks. This means your heating system may have a flame error. There might be an issue with its gas supply, gas valve or ignitor control. Call us at 763-276-0617 for support.
  8. A single light flickers slowly while the other is steady. This typically signifies your HVAC system’s limit switch is malfunctioning. The switch stops your heating system from getting too hot. Get in touch with the experts at Home Comfort Heating & Air for support.
