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

Its motherboard has twin LED lights that can display a fault code. Subject to the malfunction, your furnace may display continuous or flashing lights.

While there are a few simple heating adjustments you can finish on your own, the majority of fixes are best left to the professionals. When your heater refuses to turn on or put out warmth, get in touch with Cooler Tymes LLC at 623-208-6444 for professional furnace repair in Litchfield Park.

Our technicians will quickly identify and handle the breakdown, even if you don’t use a Lennox heating system. We can service whichever types or makes—and get the heat reintroduced to your home quickly.

What Does the Flashing Light on My Heating System Mean?

Your heater uses lights to flash code when it is malfunctioning. It also works this system to tell you it’s heating correctly.

Regular operation includes:

  • Concurrent slow flash—furnace running correctly.
  • Concurrent fast flash—heater is initiating the call for heat.

If you see a single light going on and off slowly and the other flashing fast, your heater could have a low flame signal. This can take place even when your heating system is heating correctly. It signifies the flame sensing rod may have buildup or in the wrong area on the burner. Contact us at 623-208-6444 for support.

Here are a few other of the most routine errors for Lennox heating systems.

Heater Won’t Start

Here are many of the light patterns you may observe when your heat refuses to or keep running. Most of these errors have to be handled by a professional, like one from Cooler Tymes LLC.

  1. All LED lights are extinguished. This means your heating system might not have power. Find the breaker box to make sure the heater fuse is not triggered. Try resetting the fuse if it’s in the “off” area. If it instantly trips after you reset it, don’t touch the breaker and call us at 623-208-6444.
  2. A single light is stable and the other is flashing slowly. This shows the flame rollout switch is may be malfunctioning. The switch is an essential safety mechanism that helps in avoiding fires and carbon monoxide. You shouldn’t try to fix this malfunction on your own.
  3. An individual light is flickering rapidly and the other is blinking slowly. This likely means power polarity has been reversed. Your heating system might have a wiring problem that needs expert aid from Cooler Tymes LLC.
  4. Both lights are blinking slowly. This means your furnace’s blower motor possibly isn’t working. This component circulates warm air from the heater into your home. We can aid in pinpointing what’s causing an issue with this component.
  5. One light is blinking slowly and the other is flashing quickly. This indicates your heating system might have insufficient voltage or a short circuit. Call our experts at 623-208-6444 for support.
  6. One light is flashing on, on, off while the other flashes on, off, on. This indicates there may be an issue with your HVAC system’s motherboard or wiring. Cooler Tymes LLC can locate the issue and fix it.
  7. The pair of lights are using alternating slow flickers. This indicates your HVAC equipment possibly has a flame failure. There could be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 623-208-6444 for support.
  8. A single light flashes slowly while the other remains solid. This usually signifies your heater’s limit switch is not working. The switch prevents your HVAC equipment from becoming too warm. Get in touch with the pros at Cooler Tymes LLC for assistance.
