While your Lennox® furnace can’t chat with you, it possesses a process to communicate a furnace error.

Its control panel has twin LED lights that can share a fault code. Based on the fault, your heater may show continuous or flashing lights.

Our experts will quickly detect and repair the malfunction, even if you don’t have a Lennox heater. We can service any kinds or makes—and get the comfort returned to your house quickly.

What Does the Flickering Light on My Heating System Mean?

Your heating system depends on lights to flash code when it requires repairs. It also engages this system to relay it’s working correctly.

Normal operation includes:

  • Concurrent slow flash—heating system working properly.
  • Both lights flash fast—furnace is beginning to call for heat.

If you see a solitary light flashing slowly and the other flashing fast, your furnace may be having a low flame signal. This can happen even when your heating system is running like it should. It means the flame sensing rod may have buildup or in the bad location on the burner. Call us at 717-479-4950 for help.

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

Furnace Won’t Kick On

Here are some of the light sequences you may see when your heat will not or keep running. The bulk of these errors need to be handled by a technician, for instance from Ameri-Tec.

  1. The pair of LED lights aren’t lit. This indicates your heater might not be receiving power. Find the breaker box to make sure the heater fuse isn’t flipped. You should reset the fuse if it’s in the “off” area. If it instantly flips after you reset it, don’t touch the breaker and call us at 717-479-4950.
  2. A single light is stable and the other is blinking slowly. This shows the flame rollout switch is possibly not working right. The part is an essential safety tool that helps in preventing fires and carbon monoxide. You shouldn’t try to handle this problem on your own.
  3. An individual light is blinking quickly and the other is flashing slowly. This likely indicates power polarity has been inverted. Your heater could have a wiring error that calls for specialized help from Ameri-Tec.
  4. The duo of lights are flashing slowly. This signifies your heater’s blower motor probably isn’t working. This piece sends heated air from the furnace into your home. We can help in determining what’s wrong with this part.
  5. One light is blinking slowly and the other is flashing rapidly. This means your heater might have insufficient voltage or a short circuit. Contact our experts at 717-479-4950 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This indicates there could be trouble with your heater’s control board or wiring. Ameri-Tec can pinpoint the error and take care of it.
  7. Both lights are using alternating slow flashes. This means your HVAC equipment may have a flame issue. There could be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 717-479-4950 for assistance.
  8. A single light flickers slowly while the other is continuous. This usually means your HVAC equipment’s limit switch is malfunctioning. The switch keeps your heater from becoming too warm. Get in touch with the pros at Ameri-Tec for support.

Heater Blower Operates But No Heat

Here’s what could be wrong when you hear your heating equipment’s blower fan on, but you aren’t receiving any warm air.

  • The duo of lights are showing alternate quick flashes. This signifies your furnace ignitor may be broken. This component ignites gas in your furnace to produce heat and should be repaired by a technician from Ameri-Tec.
