While your Lennox® furnace cannot speak to you, it possesses a way to tell you about a furnace error.

Its control panel has two LED lights that can display a fault code. Based on the malfunction, your heating system might use continuous or flashing lights.

While there are certain basic heating repairs you can complete yourself, most repairs are best handled by experts. When your heater refuses to kick on or give heated air, call Comfort Zone, LLC at 239-214-0411 for experienced furnace repair in Cape Coral.

Our experts will swiftly determine and fix the issue, even if you don’t own a Lennox heater. We can service whichever types or configuration—and get the warmth reintroduced to your residence fast.

What Does the Flickering Light on My Heating System Mean?

Your heater depends on lights to flash code when it is malfunctioning. It also works these lights to let you know it’s heating correctly.

Regular operation includes:

  • Simultaneous slow flash—heating system running like it should.
  • Simultaneous fast flash—furnace is initiating the call for heat.

If you realize that a solitary light flashing slowly and the other blinking rapidly, your furnace could have a low flame signal. This can take place even when your heating system is working like it should. It indicates the flame sensing rod may need to be cleaned or in the wrong area on the burner. Call us at 239-214-0411 for assistance.

Here are some of the most common problems for Lennox heating systems.

Furnace Won’t Start

Here are some of the light patterns you could see when your heating system won’t turn on or keep heating. The majority of these problems have to be repaired by a specialist, such as one from Comfort Zone, LLC.

  1. Both LED lights are extinguished. This means your HVAC system might not be receiving power. Examine the breaker box to make sure the furnace fuse has not tripped. Try resetting the fuse if it’s in the “off” area. If it instantly turns off after you reset it, don’t try to reset it again and contact us at 239-214-0411.
  2. One light is continuous and the other is blinking slowly. This implies the flame rollout switch is may be open. The switch is an essential safety tool that helps in stopping fires and carbon monoxide. You shouldn’t try to repair this malfunction yourself.
  3. One light is blinking quickly and the other is flickering slowly. This likely signifies power polarity has been transposed. Your furnace could have a wiring problem that calls for expert support from Comfort Zone, LLC.
  4. The pair of lights are flashing slowly. This means your furnace’s blower motor possibly isn’t working. This piece circulates heated air from the HVAC system into your space. We can aid in figuring out what’s causing a problem with this piece.
  5. One light is flashing slowly and the other is flashing quickly. This indicates your HVAC system could have not enough voltage or a short circuit. Get in touch with our experts at 239-214-0411 for help.
  6. One light is flashing on, on, off while the other blinks on, off, on. This means there may be trouble with your heater’s control board or wiring. Comfort Zone, LLC can pinpoint the error and fix it.
  7. Both lights display alternating slow blinks. This means your HVAC system likely has a flame failure. There might be a problem with its gas supply, gas valve or ignitor control. Call us at 239-214-0411 for support.
  8. An individual light flashes slowly while the other remains continuous. This usually means your HVAC equipment’s limit switch is experiencing an error. The switch stops your heating system from overheating. Get in touch with the experts at Comfort Zone, LLC for support.

Furnace Blower Works But No Warmth

Here’s what may be wrong when you notice your heating system’s blower fan working, but you aren’t receiving any warm air.

  • The pair of lights are showing alternate rapid blinks. This signifies your furnace ignitor could be broken. This component ignites fuel in your heater to make heat and should be fixed by a specialist from Comfort Zone, LLC.
