While your Lennox® HVAC equipment can’t chat with you, it does have a process to communicate a furnace error.

Its control board has a set of LED lights that can share a fault code. Subject to the malfunction, your heating system might use continuous or flashing lights.

Our experts will swiftly discover and fix the problem, even if you don’t use a Lennox heater. We can fix whichever brands or configuration—and get the comfort returned to your residence without delay.

What Does the Blinking Light on My Furnace Mean?

Your heater relies on lights to flash code when it isn’t working right. It also engages this setup to relay it’s working correctly.

Regular heating involves:

  • Concurrent slow flash—heater heating correctly.
  • Concurrent fast flash—heating system is starting to call for heat.

If you realize that a lone light going on and off slowly and the other blinking fast, your furnace might be experiencing a low flame signal. This can take place even when your furnace is working like it should. It means the flame sensing rod might be dirty or in the bad location on the burner. Contact us at 208-621-0129 for support.

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

Furnace Will Not Start

Here are a few of the light patterns you may notice when your heat won’t turn on or keep heating. Most of these problems need to be handled by a specialist, like one from Vogts Heating & Air.

  1. The pair of LED lights aren’t lit. This indicates your heating system might not have electricity. Examine the breaker box to confirm the heating system fuse is not flipped. Try resetting the fuse if it’s in the “off” position. If it immediately flips after you reset it, don’t touch the breaker and contact us at 208-621-0129.
  2. A single light is unchanging and the other is flickering slowly. This shows the flame rollout switch is likely malfunctioning. The part is an essential safety guard that helps in preventing fires and carbon monoxide. You shouldn’t seek to take care of this fault on your own.
  3. An individual light is flashing rapidly and the other is flickering slowly. This likely means power polarity has been transposed. Your furnace might have a wiring fault that calls for specialized help from Vogts Heating & Air.
  4. Both lights are flashing slowly. This signifies your heater’s blower motor possibly isn’t running. This part moves heated air from the heater into your space. We can aid in figuring out what’s wrong with this component.
  5. One light is flashing slowly and the other is flashing quickly. This means your heating system could have insufficient voltage or a short circuit. Call our technicians at 208-621-0129 for help.
  6. One light is blinking on, on, off while the other flashes on, off, on. This indicates there may be an issue with your heater’s control board or wiring. Vogts Heating & Air can pinpoint the issue and fix it.
  7. The pair of lights are using alternate slow flickers. This signifies your HVAC system likely has a flame problem. There may be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 208-621-0129 for support.
  8. An individual light blinks slowly while the other remains solid. This typically means your heating system’s limit switch is malfunctioning. The switch prevents your heating system from becoming too warm. Reach out to the pros at Vogts Heating & Air for assistance.

Heating System Blower Operates But No Warmth

Here’s what could be wrong when you notice your heating equipment’s blower fan on, but you aren’t receiving any warmth.

  • The duo of lights are showing every other rapid flashes. This signifies your furnace ignitor could not be working. This component ignites gas in your HVAC equipment to create warm air and should be fixed by a technician from Vogts Heating & Air.
