While your Lennox® HVAC equipment isn’t able to speak to you, it possesses a process to get your attention when there’s a furnace error.

Its motherboard has twin LED lights that can display a fault code. Based on the fault, your heater might show solid or flashing lights.

What Does the Blinking Light on My Heater Mean?

Your heating system depends on lights to flash code when it is malfunctioning. It also works this system to relay it’s operating like it should.

Correct heating includes:

  • Concurrent slow flash—heater running properly.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you realize that a lone light blinking slowly and the other blinking rapidly, your heater may be having a low flame signal. This can occur even when your heater is running like it should. It indicates the flame sensing rod might need to be cleaned or in the wrong location on the burner. Reach out to us at 505-226-3525 for support.

Here are several other of the most common issues for Lennox heating systems.

Heating System Won’t Start

Here are many of the light arrangements you could see when your heat won’t turn on or keep running. Most of these issues have to be repaired by a professional, like one from Tru Air Systems LLC.

  1. The pair of LED lights are off. This means your HVAC system might not have electricity. Examine the breaker box to make sure the heating system fuse is not flipped. You should reset the fuse if it’s in the “off” spot. If it promptly flips after a subsequent reset, don’t try to reset it again and get in touch with us us at 505-226-3525.
  2. One light is continuous and the other is flashing slowly. This signifies the flame rollout switch is possibly not working right. The part is a critical safety guard that aids in stopping fires and carbon monoxide. You shouldn’t attempt to repair this fault without professional help.
  3. A single light is flashing rapidly and the other is blinking slowly. This likely means power polarity has been reversed. Your furnace may have a wiring error that calls for professional help from Tru Air Systems LLC.
  4. The duo of lights are blinking slowly. This indicates your furnace’s blower motor probably isn’t running. This piece distributes hot air from the heater into your space. We can assist in pinpointing what’s causing an issue with this component.
