While your Lennox® furnace isn’t able to talk to you, it does have a procedure to tell you about a furnace error.

Its control board has double LED lights that can share a fault code. Subject to the problem, your furnace may use steady or flashing lights.

Although there are some elementary furnace adjustments you can take care of without an expert, the majority of fixes are best handled by the professionals. When your furnace won’t start or provide heated air, contact West Michigan Heating & Air Conditioning Services at (616) 319-1436 for professional furnace repair in Hudsonville.

Our technicians will quickly detect and take care of the breakdown, even if you don’t use a Lennox heater. We can fix all types or makes—and get the warmth returned to your house fast.

What Does the Flickering Light on My Heater Mean?

Your heating system uses lights to flash code when it is malfunctioning. It also works this system to tell you it’s working properly.

Normal function includes:

  • Concurrent slow flash—heating system running properly.
  • Simultaneous fast flash—furnace is starting to call for heat.

If you see a single light going on and off slowly and the other flashing rapidly, your furnace may be experiencing a low flame signal. This can occur even when your heater is operating properly. It means the flame sensing rod may need to be cleaned or in the wrong location on the burner. Call us at (616) 319-1436 for help.

Here are a few other of the most common faults for Lennox furnaces.

Heating System Won’t Start

Here are a few of the light patterns you might see when your heating system won’t turn on or keep running. The majority of these errors need to be repaired by a technician, such as one from West Michigan Heating & Air Conditioning Services.

  1. The pair of LED lights are off. This indicates your heating system might not be receiving power. Look at the breaker box to ensure the furnace fuse has not flipped. You should reset the fuse if it is in the “off” position. If it immediately turns off after you reset it, don’t touch the breaker and call us at (616) 319-1436.
  2. A single light is unchanging and the other is flashing slowly. This signifies the flame rollout switch is likely open. The component is a critical safety tool that helps in preventing fires and carbon monoxide. You shouldn’t seek to take care of this issue yourself.
  3. An individual light is blinking quickly and the other is flashing slowly. This often means power polarity has been reversed. Your furnace may have a wiring issue that requires specialized assistance from West Michigan Heating & Air Conditioning Services.
  4. The duo of lights are flickering slowly. This signifies your heater’s blower motor possibly isn’t working. This piece distributes heated air from the HVAC system into your home. We can aid in figuring out what’s wrong with this piece.
  5. A single light is flickering slowly and the other is flashing rapidly. This means your heating system may have not enough voltage or a short circuit. Contact our specialists at (616) 319-1436 for assistance.
  6. One light is flashing on, on, off while the other flashes on, off, on. This means there might be a fault with your HVAC system’s control panel or wiring. West Michigan Heating & Air Conditioning Services can pinpoint the fault and fix it.
  7. The duo of lights show alternate slow flashes. This means your heating system may have a flame problem. There may be a problem with its gas supply, gas valve or ignitor control. Call us at (616) 319-1436 for support.
  8. A single light flickers slowly while the other remains solid. This typically indicates your heating system’s limit switch is malfunctioning. The switch stops your heating system from becoming too warm. Reach out to the experts at West Michigan Heating & Air Conditioning Services for assistance.

Heating System Blower Runs But No Warm Air

Here’s what may be at fault when you observe your heating system’s blower fan on, but you aren’t receiving any heated air.

  • The pair of lights display alternate quick blinks. This indicates your furnace ignitor could be broken. This part ignites fuel in your heating system to make heat and should be serviced by an expert from West Michigan Heating & Air Conditioning Services.
