While your Lennox® heating system cannot speak to you, it has a method to tell you about a furnace error.

Its control board has double LED lights that can show a fault code. Depending on the malfunction, your furnace might display continuous or flashing lights.

Although there are a few elementary HVAC fixes you can take care of yourself, the majority of tasks are best handled by the professionals. When your heating system refuses to kick on or put out heated air, contact Brookwood Inc at 641-316-9803 for professional furnace repair in Newton.

Our specialists will rapidly detect and handle the malfunction, even if you don’t use a Lennox heater. We can service any kinds or configuration—and get the warmth reintroduced to your home fast.

What Does the Flickering Light on My Heater Mean?

Your furnace relies on lights to flash code when it is malfunctioning. It also uses this setup to tell you it’s operating like it should.

Correct heating involves:

  • Simultaneous slow flash—heating system operating like it should.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you realize that a lone light flashing slowly and the other going on and off fast, your furnace could be experiencing a low flame signal. This can take place even when your heater is working properly. It indicates the flame sensing rod could be dirty or in the wrong area on the burner. Call us at 641-316-9803 for help.

Here are a few other of the most routine problems for Lennox furnaces.

Furnace Refuses to Start

Here are some of the light patterns you might notice when your heat won’t turn on or keep running. Most of these errors need to be taken care of by a technician, such as one from Brookwood Inc.

  1. Both LED lights are extinguished. This means your heater might not be receiving power. Go to the breaker box to ensure the furnace fuse has not triggered. You should reset the fuse if it’s in the “off” position. If it instantly turns off after a subsequent reset, don’t try to reset it again and contact us at 641-316-9803.
  2. A single light is stable and the other is flickering slowly. This signifies the flame rollout switch is may be not working right. The switch is an essential safety tool that helps in stopping fires and carbon monoxide. You shouldn’t try to repair this fault on your own.
  3. An individual light is flashing quickly and the other is blinking slowly. This typically signifies power polarity has been transposed. Your furnace may have a wiring issue that calls for professional aid from Brookwood Inc.
  4. The duo of lights are flickering slowly. This indicates your furnace’s blower motor possibly isn’t operating. This component sends warm air from the HVAC system into your residence. We can help in determining what’s causing a problem with this component.
  5. An individual light is flickering slowly and the other is flickering fast. This means your heater could have insufficient voltage or a short circuit. Reach out to our technicians at 641-316-9803 for help.
  6. One light is flickering on, on, off while the other blinks on, off, on. This means there could be an issue with your HVAC system’s control panel or wiring. Brookwood Inc can determine the issue and fix it.
  7. Both lights are using alternate slow flashes. This indicates your heating system likely has a flame error. There could be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 641-316-9803 for support.
  8. A single light flickers slowly while the other stays steady. This typically signifies your heater’s limit switch is malfunctioning. The switch stops your HVAC system from getting too hot. Call the specialists at Brookwood Inc for help.

Heater Blower Works But No Heat

Here’s what might be at fault when you observe your heating equipment’s blower fan on, but you aren’t getting any warm air.

  • The duo of lights are giving every other rapid blinks. This means your furnace ignitor might be broken. This piece ignites gas in your heater to create warm air and should be fixed by an expert from Brookwood Inc.
