While your Lennox® heating system cannot chat with you, it has a process to tell you about a furnace error.

Its control panel has two LED lights that can show a fault code. Depending on the problem, your furnace could display continuous or flashing lights.

Although there are a few elementary furnace adjustments you can take care of on your own, most repairs are best taken care of by experts. When your heater will not start or give warmth, call Comfort Concepts Heating & Air Conditioning at 405-494-7444 for expert furnace repair in Yukon.

Our technicians will quickly determine and repair the malfunction, even if you don’t own a Lennox heater. We can repair all brands or configuration—and get the heat returned to your home fast.

What Does the Blinking 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 operating like it should.

Regular function includes:

  • Simultaneous slow flash—furnace working like it should.
  • Both lights flash fast—heating system is beginning to call for heat.

If you notice a solitary light going on and off slowly and the other going on and off quickly, your heater may be experiencing a low flame signal. This can occur even when your heating system is heating properly. It indicates the flame sensing rod might need to be cleaned or in the incorrect area on the burner. Contact us at 405-494-7444 for assistance.

Here are several other of the most common issues for Lennox furnaces.

Furnace Will Not Turn On

Here are many of the light arrangements you could see when your furnace refuses to or keep running. Most of these problems need to be handled by a professional, such as one from Comfort Concepts Heating & Air Conditioning.

  1. All LED lights are off. This means your heater might not be receiving power. Find the breaker box to confirm the heating system fuse hasn’t tripped. Try resetting the fuse if it’s in the “off” area. If it rapidly turns off after a subsequent reset, don’t touch the breaker and get in touch with us us at 405-494-7444.
  2. A single light is stable and the other is flickering slowly. This shows the flame rollout switch is likely open. The switch is an essential safety mechanism that helps in avoiding fires and carbon monoxide. You shouldn’t try to handle this problem yourself.
  3. A single light is flashing quickly and the other is flickering slowly. This often means power polarity has been reversed. Your furnace may have a wiring fault that requires expert help from Comfort Concepts Heating & Air Conditioning.
  4. The duo of lights are blinking slowly. This signifies your furnace’s blower motor probably isn’t running. This piece distributes heated air from the furnace into your house. We can assist in pinpointing what’s causing an issue with this piece.
  5. A single light is blinking slowly and the other is blinking rapidly. This indicates your heater could have insufficient voltage or a short circuit. Reach out to our experts at 405-494-7444 for help.
  6. One light is flickering on, on, off while the other flashes on, off, on. This indicates there could be trouble with your heater’s control board or wiring. Comfort Concepts Heating & Air Conditioning can locate the issue and repair it.
  7. The pair of lights display alternating slow blinks. This signifies your heating system likely has a flame error. There may be an issue with its gas supply, gas valve or ignitor control. Get in touch with us at 405-494-7444 for support.
  8. An individual light flashes slowly while the other remains steady. This typically indicates your HVAC equipment’s limit switch is malfunctioning. The switch prevents your heating system from overheating. Reach out to the professionals at Comfort Concepts Heating & Air Conditioning for help.

Heating System Blower Runs But No Warm Air

Here’s what may be at fault when you observe your heater’s blower fan working, but you aren’t receiving any warm air.

  • The pair of lights are showing alternate fast flickers. This indicates your furnace ignitor might not be in working order. This piece ignites gas in your HVAC equipment to make warmth and should be fixed by a technician from Comfort Concepts Heating & Air Conditioning.
