While your Lennox® HVAC equipment cannot speak to you, it has a way to communicate a furnace error.

Its motherboard has twin LED lights that can show a fault code. Based on the problem, your heating system could show continuous or flashing lights.

While there are certain simple furnace adjustments you can take care of on your own, the majority of services are best left to the professionals. When your furnace will not turn on or provide warmth, contact Watts Electric & AC at 601-736-7362 for skilled furnace repair in Columbia.

Our experts will speedily determine and repair the breakdown, even if you don’t use a Lennox heating system. We can fix all kinds or makes—and get the comfort returned to your house fast.

What Does the Flickering Light on My Heating System Mean?

Your furnace relies on lights to flash code when it requires repairs. It also engages these lights to relay it’s working correctly.

Normal heating consists of:

  • Concurrent slow flash—heating system operating correctly.
  • Concurrent fast flash—heater is beginning to call for heat.

If you see a single light flashing slowly and the other flashing quickly, your heater could have a low flame signal. This can happen even when your heater is operating properly. It means the flame sensing rod might have buildup or in the bad spot on the burner. Reach out to us at 601-736-7362 for support.

Here are several other of the most routine faults for Lennox furnaces.

Furnace Will Not Turn On

Here are some of the light patterns you could notice when your furnace refuses to or keep heating. Most of these problems must be handled by a professional, like one from Watts Electric & AC.

  1. The pair of LED lights are off. This means your heating system might not be receiving power. Go to the breaker box to confirm the furnace fuse hasn’t tripped. Attempt to reset the fuse if it is in the “off” spot. If it instantly trips after a subsequent reset, don’t touch the breaker and contact us at 601-736-7362.
  2. An individual light is continuous and the other is flashing slowly. This shows the flame rollout switch is may be open. The part is an essential safety tool that helps in avoiding fires and carbon monoxide. You shouldn’t seek to fix this malfunction on your own.
  3. A single light is flashing fast and the other is blinking slowly. This likely means power polarity has been reversed. Your furnace could have a wiring issue that calls for specialized support from Watts Electric & AC.
  4. Both lights are blinking slowly. This signifies your heating system’s blower motor probably isn’t running. This piece distributes hot air from the HVAC system into your home. We can aid in determining what’s causing an issue with this part.
  5. An individual light is blinking slowly and the other is flashing quickly. This signifies your HVAC system might have not enough voltage or a short circuit. Reach out to our experts at 601-736-7362 for assistance.
  6. One light is flickering on, on, off while the other blinks on, off, on. This means there may be trouble with your heater’s control panel or wiring. Watts Electric & AC can determine the issue and handle it.
  7. The duo of lights display alternate slow flashes. This signifies your HVAC system may have a flame error. There may be trouble with its gas supply, gas valve or ignitor control. Contact us at 601-736-7362 for support.
  8. A single light blinks slowly while the other is steady. This usually means your heating system’s limit switch is experiencing an error. The switch stops your heating system from getting too hot. Call the specialists at Watts Electric & AC for assistance.

Heater Blower Runs But No Warmth
