While your Lennox® heating system isn’t able to chat with you, it possesses a way to get your attention when there’s a furnace error.

Its motherboard has a set of LED lights that can show a fault code. Depending on the failure, your furnace might use continuous or flashing lights.

Although there are various basic heating fixes you can complete on your own, many fixes are best left to the professionals. When your heating system won’t start or provide heat, reach out to JBR Mechanical at 812-266-9785 for skilled furnace repair in Bedford.

Our experts will quickly discover and handle the malfunction, even if you don’t use a Lennox heater. We can service whichever kinds or models—and get the warmth returned to your residence quickly.

What Does the Blinking Light on My Heater Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also engages these lights to let you know it’s working properly.

Normal heating involves:

  • Concurrent slow flash—furnace operating like it should.
  • Both lights flash fast—heating system is beginning to call for heat.

If you realize that a lone light blinking slowly and the other blinking rapidly, your heater could be experiencing a low flame signal. This can occur even when your heating system is running like it should. It means the flame sensing rod may be dirty or in the wrong spot on the burner. Contact us at 812-266-9785 for assistance.

Here are a few other of the most routine issues for Lennox heaters.

Heating System Will Not Turn On

Here are many of the light arrangements you may observe when your heating system won’t turn on or keep running. Most of these problems must be repaired by a technician, such as one from JBR Mechanical.

  1. The duo of LED lights aren’t lit. This indicates your HVAC system might not have power. Examine the breaker box to ensure the heater fuse isn’t flipped. Try resetting the fuse if it is in the “off” spot. If it promptly flips after a subsequent reset, don’t touch the breaker and call us at 812-266-9785.
  2. An individual light is stable and the other is flashing slowly. This shows the flame rollout switch is likely malfunctioning. The switch is an essential safety tool that helps in preventing fires and carbon monoxide. You shouldn’t seek to fix this fault without professional help.
  3. A single light is flickering fast and the other is blinking slowly. This often signifies power polarity has been reversed. Your furnace might have a wiring error that calls for expert support from JBR Mechanical.
  4. The pair of lights are flashing slowly. This means your furnace’s blower motor probably isn’t working. This component circulates hot air from the heating system into your residence. We can assist in determining what’s causing a problem with this component.
  5. A single light is flickering slowly and the other is flashing quickly. This means your HVAC system might have low voltage or a short circuit. Call our technicians at 812-266-9785 for assistance.
  6. One light is flashing on, on, off while the other blinks on, off, on. This means there could be an issue with your heater’s control board or wiring. JBR Mechanical can locate the issue and repair it.
  7. The duo of lights are using alternating slow blinks. This means your HVAC equipment likely has a flame issue. There could be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 812-266-9785 for support.
  8. A single light flickers slowly while the other stays continuous. This typically indicates your HVAC system’s limit switch is not working. The switch keeps your HVAC equipment from getting too hot. Reach out to the pros at JBR Mechanical for support.

Heating System Blower Runs But No Warmth
