While your Lennox® heater isn’t able to chat with you, it has a way to tell you about a furnace error.

Its control board has double LED lights that can share a fault code. Subject to the issue, your furnace might show continuous or flashing lights.

Although there are a few elementary furnace adjustments you can complete on your own, the majority of services are best left to experts. When your furnace will not kick on or give heated air, reach out to All Weather Heating & Air Conditioning Inc at 256-801-4701 for skilled furnace repair in Huntsville.

Our technicians will rapidly determine and handle the breakdown, even if you don’t use a Lennox heater. We can fix all brands or models—and get the heat reintroduced to your residence quickly.

What Does the Flickering Light on My Heater Mean?

Your furnace relies on lights to flash code when it requires repairs. It also uses these lights to let you know it’s heating like it should.

Correct function involves:

  • Concurrent slow flash—heater running correctly.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you realize that a solitary light blinking slowly and the other going on and off fast, your heating system could be experiencing a low flame signal. This can take place even when your heating system is running correctly. It indicates the flame sensing rod may be dirty or in the bad location on the burner. Contact us at 256-801-4701 for assistance.

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

Heater Refuses to Kick On

Here are a few of the light patterns you may see when your heat refuses to or keep heating. Most of these issues have to be handled by a specialist, like one from All Weather Heating & Air Conditioning Inc.

  1. Both LED lights aren’t lit. This indicates your heater might not be receiving power. Find the breaker box to confirm the heater fuse isn’t triggered. Try resetting the fuse if it is in the “off” position. If it immediately turns off following a reset, don’t try to reset it again and contact us at 256-801-4701.
  2. An individual light is continuous and the other is blinking slowly. This implies the flame rollout switch is possibly malfunctioning. The switch is an essential safety mechanism that assists in preventing fires and carbon monoxide. You shouldn’t try to fix this fault yourself.
  3. An individual light is blinking quickly and the other is flickering slowly. This often signifies power polarity has been transposed. Your furnace could have a wiring error that requires specialized assistance from All Weather Heating & Air Conditioning Inc.
  4. All lights are flashing slowly. This indicates your heater’s blower motor probably isn’t working. This piece circulates hot air from the heater into your house. We can aid in figuring out what’s causing a problem with this component.
  5. A single light is blinking slowly and the other is blinking rapidly. This means your heater might have insufficient voltage or a short circuit. Get in touch with our specialists at 256-801-4701 for assistance.
  6. One light is flashing on, on, off while the other flashes on, off, on. This means there may be trouble with your heater’s control board or wiring. All Weather Heating & Air Conditioning Inc can determine the issue and handle it.
  7. The pair of lights are using alternate slow flickers. This indicates your HVAC system may have a flame error. There may be a problem with its gas supply, gas valve or ignitor control. Call us at 256-801-4701 for help.
  8. An individual light flashes slowly while the other stays steady. This often indicates your heating system’s limit switch is experiencing an error. The switch prevents your heating system from overheating. Get in touch with the experts at All Weather Heating & Air Conditioning Inc for help.

Furnace Blower Runs But No Heat

Here’s what could be wrong when you hear your heating system’s blower fan running, but you aren’t gaining any heated air.

  • The duo of lights are showing alternate quick blinks. This means your furnace ignitor may not be in working order. This piece lights gas in your heating system to produce warmth and should be repaired by an expert from All Weather Heating & Air Conditioning Inc.
