While your Lennox® HVAC equipment cannot speak to you, it does have a way to get your attention when there’s a furnace error.

Its control panel has a set of LED lights that can display a fault code. Based on the problem, your furnace may use solid or flashing lights.

Although there are a few simple heating adjustments you can finish without an expert, most fixes are best handled by experts. When your heating system refuses to turn on or provide heated air, call Mountain Air at 304-413-1287 for expert furnace repair in Morgantown.

Our technicians will swiftly discover and take care of the problem, even if you don’t use a Lennox heater. We can service all brands or configuration—and get the heat reintroduced to your house quickly.

What Does the Flashing Light on My Heating System Mean?

Your heater relies on lights to flash code when it is malfunctioning. It also works this setup to tell you it’s operating like it should.

Correct heating includes:

  • Simultaneous slow flash—furnace operating properly.
  • Simultaneous fast flash—furnace is starting to call for heat.

If you notice a lone light blinking slowly and the other going on and off rapidly, your furnace might be having a low flame signal. This can occur even when your furnace is heating like it should. It signifies the flame sensing rod might have buildup or in the bad area on the burner. Contact us at 304-413-1287 for help.

Here are a few other of the most typical errors for Lennox HVAC systems.

Heater Refuses to Kick On

Here are some of the light patterns you might see when your heating system won’t turn on or keep operating. The bulk of these problems need to be taken care of by a specialist, for instance from Mountain Air.

  1. Both LED lights aren’t lit. This means your heater might not be receiving power. Go to the breaker box to ensure the heater fuse is not flipped. You should reset the fuse if it’s in the “off” spot. If it instantly flips after a subsequent reset, don’t try to reset it again and call us at 304-413-1287.
  2. An individual light is continuous and the other is flashing slowly. This implies the flame rollout switch is possibly not working right. The switch is an essential safety tool that aids in preventing fires and carbon monoxide. You shouldn’t try to repair this problem without professional help.
  3. A single light is flashing fast and the other is blinking slowly. This likely means power polarity has been inverted. Your furnace may have a wiring error that requires professional aid from Mountain Air.
  4. The duo of lights are blinking slowly. This signifies your heating system’s blower motor probably isn’t working. This piece circulates heated air from the HVAC system into your house. We can help in figuring out what’s wrong with this piece.
  5. An individual light is flickering slowly and the other is flashing rapidly. This indicates your heater may have insufficient voltage or a short circuit. Get in touch with our technicians at 304-413-1287 for assistance.
  6. One light is flashing on, on, off while the other flickers on, off, on. This indicates there might be a fault with your HVAC system’s control panel or wiring. Mountain Air can find the problem and repair it.
  7. The pair of lights are using alternating slow blinks. This means your HVAC system likely has a flame issue. There might be a problem with its gas supply, gas valve or ignitor control. Call us at 304-413-1287 for support.
  8. An individual light blinks slowly while the other is solid. This typically signifies your heater’s limit switch is not working. The switch keeps your heater from getting too hot. Call the professionals at Mountain Air for help.

Heater Blower Runs But No Warm Air

Here’s what could be at fault when you hear your heating equipment’s blower fan running, but you aren’t getting any warm air.

  • The pair of lights display alternate fast flashes. This indicates your furnace ignitor may not be in working order. This part ignites fuel in your HVAC equipment to create warmth and should be fixed by a specialist from Mountain Air.
