While your Lennox® HVAC equipment isn’t able to chat with you, it does have a way to tell you about a furnace error.

Its control panel has two LED lights that can share a fault code. Based on the issue, your furnace could show continuous or flashing lights.

While there are a few simple heating repairs you can do yourself, many fixes are best taken care of by experts. When your heater will not turn on or deliver heated air, reach out to Select Comfort Systems at 801-305-4777 for expert furnace repair in West Valley City.

Our experts will speedily determine and take care of the problem, even if you don’t use a Lennox heating system. We can fix whichever brands or configuration—and get the warmth reintroduced to your home quickly.

What Does the Flashing Light on My Heating System Mean?

Your furnace uses lights to flash code when it isn’t working right. It also uses these lights to tell you it’s operating like it should.

Regular operation consists of:

  • Simultaneous slow flash—heater working like it should.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you notice a lone light blinking slowly and the other flashing fast, your heating system might be experiencing a low flame signal. This can take place even when your furnace is operating like it should. It signifies the flame sensing rod may need to be cleaned or in the bad location on the burner. Call us at 801-305-4777 for support.

Here are several other of the most routine problems for Lennox HVAC systems.

Heater Refuses to Turn On

Here are many of the light arrangements you could notice when your furnace refuses to or keep operating. Most of these issues need to be repaired by a technician, for instance from Select Comfort Systems.

  1. All LED lights are extinguished. This signifies your heating system might not be receiving power. Go to the breaker box to make sure the heater fuse hasn’t triggered. Attempt to reset the fuse if it’s in the “off” position. If it rapidly turns off following a reset, don’t try to reset it again and contact us at 801-305-4777.
  2. An individual light is continuous and the other is blinking slowly. This signifies the flame rollout switch is possibly open. The component is a critical safety tool that helps in stopping fires and carbon monoxide. You shouldn’t try to handle this malfunction yourself.
  3. An individual light is flickering fast and the other is blinking slowly. This likely indicates power polarity has been reversed. Your furnace could have a wiring fault that calls for expert assistance from Select Comfort Systems.
  4. All lights are flashing slowly. This indicates your heating system’s blower motor probably isn’t running. This piece sends warm air from the furnace into your residence. We can assist in pinpointing what’s wrong with this part.
  5. One light is flickering slowly and the other is flickering quickly. This indicates your HVAC system could have low voltage or a short circuit. Contact our specialists at 801-305-4777 for assistance.
  6. One light is flashing on, on, off while the other blinks on, off, on. This signifies there could be trouble with your HVAC system’s control panel or wiring. Select Comfort Systems can find the error and fix it.
  7. Both lights are using alternate slow flashes. This indicates your HVAC 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 801-305-4777 for assistance.
  8. An individual light flickers slowly while the other stays steady. This usually indicates your heater’s limit switch is experiencing an error. The switch stops your HVAC equipment from getting too hot. Get in touch with the professionals at Select Comfort Systems for support.

Furnace Blower Runs But No Warmth

Here’s what might be at fault when you notice your heating equipment’s blower fan running, but you aren’t gaining any warm air.

  • The pair of lights are giving every other rapid flickers. This means your furnace ignitor could not be working. This part ignites gas in your heating system to produce warmth and should be fixed by a specialist from Select Comfort Systems.
