While your Lennox® heating system can’t talk to you, it has a way to tell you about a furnace error.

Its motherboard has two LED lights that can share a fault code. Subject to the fault, your heating system might show continuous or flashing lights.

Although there are a few simple HVAC adjustments you can take care of without an expert, most services are best handled by experts. When your heater refuses to kick on or give heated air, call Verona HVAC at 818-306-3387 for skilled furnace repair in Santa Clarita.

Our experts will rapidly identify and take care of the issue, even if you don’t own a Lennox heater. We can service any types or configuration—and get the comfort reintroduced to your residence quickly.

What Does the Flashing Light on My Heating System Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also uses this system to relay it’s working correctly.

Normal operation consists of:

  • Concurrent slow flash—heater working correctly.
  • Both lights flash fast—furnace is starting to call for heat.

If you realize that a lone light flashing slowly and the other blinking fast, your furnace may be experiencing a low flame signal. This can happen even when your furnace is heating properly. It signifies the flame sensing rod may be dirty or in the bad spot on the burner. Call us at 818-306-3387 for help.

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

Furnace Will Not Start

Here are many of the light arrangements you might notice when your heater refuses to or keep running. Most of these problems have to be handled by an expert, like one from Verona HVAC.

  1. The duo of LED lights aren’t lit. This indicates your heater might not have electricity. Look at the breaker box to ensure the heater fuse is not flipped. Try resetting the fuse if it is in the “off” spot. If it immediately turns off following a reset, don’t touch the breaker and call us at 818-306-3387.
  2. An individual light is stable and the other is flashing slowly. This implies the flame rollout switch is likely malfunctioning. The component is an essential safety mechanism that helps in preventing fires and carbon monoxide. You shouldn’t seek to fix this issue without professional help.
  3. An individual light is blinking rapidly and the other is flashing slowly. This typically indicates power polarity has been reversed. Your heating system could have a wiring error that calls for expert assistance from Verona HVAC.
  4. Both lights are flickering slowly. This signifies your heater’s blower motor probably isn’t working. This component circulates hot air from the heater into your home. We can help in pinpointing what’s causing an issue with this piece.
  5. A single light is flickering slowly and the other is blinking rapidly. This means your heater could have low voltage or a short circuit. Call our experts at 818-306-3387 for support.
  6. One light is blinking on, on, off while the other flickers on, off, on. This indicates there could be an issue with your heating system’s motherboard or wiring. Verona HVAC can locate the error and fix it.
  7. Both lights display alternate slow flashes. This signifies your heater likely has a flame error. There could be an issue with its gas supply, gas valve or ignitor control. Call us at 818-306-3387 for support.
  8. An individual light blinks slowly while the other is steady. This typically signifies your HVAC system’s limit switch is not working. The switch prevents your HVAC system from overheating. Call the experts at Verona HVAC for help.

Heating System Blower Runs But No Warmth

Here’s what may be wrong when you observe your heating equipment’s blower fan running, but you aren’t getting any heated air.

  • The duo of lights display alternate fast blinks. This means your furnace ignitor might not be working. This component ignites fuel in your heating system to create heat and should be fixed by an expert from Verona HVAC.
