While your Lennox® furnace cannot chat with you, it has a procedure to communicate a furnace error.

Its control panel has double LED lights that can share a fault code. Depending on the malfunction, your heating system may display solid or flashing lights.

Our experts will speedily identify and fix the problem, even if you don’t have a Lennox heating system. We can repair all types or models—and get the comfort reintroduced to your house without delay.

What Does the Flickering Light on My Furnace Mean?

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

Correct heating involves:

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

If you notice a single light blinking slowly and the other blinking quickly, your furnace might have a low flame signal. This can occur even when your heater is heating properly. It means the flame sensing rod could have buildup or in the bad spot on the burner. Call us at 208-561-1226 for help.

Here are a few other of the most routine faults for Lennox HVAC systems.

Furnace Won’t Start

Here are some of the light arrangements you might see when your furnace will not or keep operating. The majority of these problems must be fixed by a specialist, like one from Alpine Summit Heating & Cooling.

  1. The duo of LED lights are extinguished. This signifies your HVAC system might not have electricity. Find the breaker box to confirm the furnace fuse has not triggered. Try resetting the fuse if it is in the “off” area. If it rapidly trips after you reset it, don’t try to reset it again and get in touch with us us at 208-561-1226.
  2. An individual light is continuous and the other is flashing slowly. This implies the flame rollout switch is possibly not working right. The component is a critical safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t seek to take care of this problem without professional help.
  3. An individual light is flickering fast and the other is blinking slowly. This likely signifies power polarity has been inverted. Your heater could have a wiring problem that calls for specialized help from Alpine Summit Heating & Cooling.
  4. The pair of lights are flashing slowly. This indicates your heater’s blower motor likely isn’t working. This part sends hot air from the heater into your residence. We can help in pinpointing what’s causing an issue with this component.
  5. An individual light is blinking slowly and the other is flickering fast. This signifies your HVAC system might have not enough voltage or a short circuit. Reach out to our experts at 208-561-1226 for support.
  6. One light is flickering on, on, off while the other flashes on, off, on. This indicates there could be a fault with your HVAC system’s control board or wiring. Alpine Summit Heating & Cooling can pinpoint the issue and handle it.
  7. Both lights show alternating slow blinks. This signifies your HVAC equipment may have a flame failure. There might be trouble with its gas supply, gas valve or ignitor control. Reach out to us at 208-561-1226 for help.
  8. An individual light flashes slowly while the other stays solid. This typically means your heater’s limit switch is not working. The switch stops your HVAC equipment from overheating. Call the pros at Alpine Summit Heating & Cooling for assistance.

Heating System Blower Operates But No Heat

Here’s what could be broken when you hear your heating system’s blower fan working, but you aren’t getting any warm air.

  • The duo of lights are showing every other rapid blinks. This means your furnace ignitor might not be working. This part ignites energy in your heating system to create warmth and should be repaired by a specialist from Alpine Summit Heating & Cooling.
