While your Lennox® HVAC equipment isn’t able to talk to you, it has a process to communicate a furnace error.

Its control panel has a set of LED lights that can show a fault code. Based on the fault, your heater could show continuous or flashing lights.

Although there are some simple HVAC adjustments you can finish yourself, most repairs are best handled by HVAC technicians. When your heater refuses to start or provide heated air, call Goode Bros AC & Heating at 903-284-2612 for professional furnace repair in Longview.

Our technicians will rapidly discover and fix the malfunction, even if you don’t own a Lennox heater. We can fix all types or models—and get the comfort reintroduced to your home quickly.

What Does the Flashing Light on My Furnace Mean?

Your heating system uses lights to flash code when it isn’t working right. It also uses this system to let you know it’s heating properly.

Regular heating includes:

  • Simultaneous slow flash—furnace operating like it should.
  • Concurrent fast flash—furnace is initiating the call for heat.

If you realize that a solitary light blinking slowly and the other going on and off quickly, your heating system could be experiencing a low flame signal. This can take place even when your furnace is heating properly. It signifies the flame sensing rod might have buildup or in the incorrect area on the burner. Reach out to us at 903-284-2612 for support.

Here are some of the most typical errors for Lennox heaters.

Heating System Refuses to Kick On

Here are some of the light arrangements you might see when your heating system won’t turn on or keep heating. Most of these errors must be fixed by a technician, such as one from Goode Bros AC & Heating.

  1. Both LED lights aren’t lit. This means your heater might not have power. Look at the breaker box to make sure the heater fuse isn’t triggered. Attempt to reset the fuse if it is in the “off” area. If it immediately trips after a subsequent reset, don’t touch the breaker and get in touch with us us at 903-284-2612.
  2. A single light is continuous and the other is blinking slowly. This shows the flame rollout switch is likely malfunctioning. The part is a critical safety tool that assists in avoiding fires and carbon monoxide. You shouldn’t try to repair this malfunction on your own.
  3. An individual light is blinking rapidly and the other is flickering slowly. This likely signifies power polarity has been transposed. Your heater might have a wiring fault that calls for expert support from Goode Bros AC & Heating.
  4. All lights are flashing slowly. This means your heating system’s blower motor likely isn’t working. This piece moves warm air from the furnace into your space. We can aid in pinpointing what’s causing an issue with this component.
  5. An individual light is flashing slowly and the other is flickering fast. This signifies your HVAC system may have not enough voltage or a short circuit. Call our technicians at 903-284-2612 for assistance.
  6. One light is blinking on, on, off while the other blinks on, off, on. This indicates there may be an issue with your heating system’s control panel or wiring. Goode Bros AC & Heating can pinpoint the problem and fix it.
  7. Both lights show alternating slow flickers. This signifies your HVAC equipment likely has a flame issue. There may be an issue with its gas supply, gas valve or ignitor control. Reach out to us at 903-284-2612 for assistance.
  8. An individual light blinks slowly while the other remains steady. This often indicates your heating system’s limit switch is not working. The switch stops your HVAC equipment from overheating. Reach out to the experts at Goode Bros AC & Heating for assistance.
