While your Lennox® heating system isn’t able to speak to you, it does have a way to tell you about a furnace error.

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

While there are some simple heating fixes you can take care of without an expert, most services are best taken care of by experts. When your heater refuses to start or give warm air, reach out to Hix Air Conditioning Service, Inc. at 918-682-8238 for experienced furnace repair in Muskogee.

Our specialists will rapidly discover and take care of the breakdown, even if you don’t own a Lennox heater. We can repair whichever types or models—and get the comfort reintroduced to your home quickly.

What Does the Blinking Light on My Heater Mean?

Your heater uses lights to flash code when it requires repairs. It also engages these lights to relay it’s operating correctly.

Normal function consists of:

  • Concurrent slow flash—furnace heating correctly.
  • Concurrent fast flash—furnace is beginning to call for heat.

If you see a single light going on and off slowly and the other flashing rapidly, your furnace could be having a low flame signal. This can take place even when your furnace is operating properly. It signifies the flame sensing rod might be dirty or in the wrong area on the burner. Contact us at 918-682-8238 for assistance.

Here are some of the most typical faults for Lennox heating systems.

Heater Won’t Turn On

Here are many of the light arrangements you could observe when your heat won’t turn on or keep heating. The majority of these issues must be fixed by a technician, for instance from Hix Air Conditioning Service, Inc..

  1. The pair of LED lights are extinguished. This indicates your HVAC system might not have power. Go to the breaker box to make sure the heating system fuse hasn’t triggered. You should reset the fuse if it is in the “off” area. If it rapidly trips after you reset it, don’t touch the breaker and contact us at 918-682-8238.
  2. An individual light is continuous and the other is blinking slowly. This shows the flame rollout switch is likely not working right. The switch is an essential safety device that helps in preventing fires and carbon monoxide. You shouldn’t attempt to take care of this fault on your own.
  3. An individual light is flickering quickly and the other is flickering slowly. This likely indicates power polarity has been inverted. Your heating system might have a wiring problem that calls for professional assistance from Hix Air Conditioning Service, Inc..
  4. The pair of lights are flickering slowly. This signifies your furnace’s blower motor likely isn’t running. This part distributes hot air from the HVAC system into your home. We can assist in determining what’s wrong with this piece.
  5. A single light is flickering slowly and the other is blinking fast. This indicates your HVAC system might have not enough voltage or a short circuit. Contact our experts at 918-682-8238 for assistance.
  6. One light is flickering on, on, off while the other blinks on, off, on. This means there may be a malfunction with your heater’s control board or wiring. Hix Air Conditioning Service, Inc. can pinpoint the error and take care of it.
  7. The duo of lights display alternate slow flickers. This means your heater may have a flame issue. There could be trouble with its gas supply, gas valve or ignitor control. Contact us at 918-682-8238 for assistance.
  8. A single light flashes slowly while the other is steady. This often indicates your HVAC equipment’s limit switch is not working. The switch prevents your heating system from overheating. Get in touch with the specialists at Hix Air Conditioning Service, Inc. for help.

Heater Blower Runs But No Heat

Here’s what could be broken when you observe your heater’s blower fan on, but you aren’t receiving any warm air.
