While your Lennox® furnace can’t speak to you, it possesses a way to tell you about a furnace error.

Its motherboard has two LED lights that can share a fault code. Depending on the issue, your furnace could display continuous or flashing lights.

Our technicians will swiftly determine and handle the problem, even if you don’t have a Lennox heater. We can repair any types or configuration—and get the warmth reintroduced to your residence quickly.

What Does the Flickering Light on My Furnace Mean?

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

Regular heating includes:

  • Simultaneous slow flash—heating system heating like it should.
  • Simultaneous fast flash—heating system is initiating the call for heat.

If you realize that a solitary light going on and off slowly and the other blinking fast, your heater may be experiencing a low flame signal. This can happen even when your furnace is operating correctly. It signifies the flame sensing rod could be dirty or in the incorrect area on the burner. Reach out to us at 276-302-0076 for help.

Here are several other of the most common issues for Lennox heaters.

Furnace Will Not Start

Here are some of the light sequences you might notice when your heat will not or keep heating. The bulk of these errors need to be handled by an expert, for instance from HCE Systems.

  1. All LED lights are extinguished. This means your heating system might not be receiving power. Examine the breaker box to confirm the heater fuse has not flipped. Try resetting the fuse if it’s in the “off” area. If it rapidly flips after you reset it, don’t try to reset it again and contact us at 276-302-0076.
  2. One light is stable and the other is blinking slowly. This shows the flame rollout switch is may be malfunctioning. The part is a critical safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t attempt to handle this problem yourself.
  3. One light is blinking fast and the other is blinking slowly. This often means power polarity has been transposed. Your furnace could have a wiring problem that requires specialized aid from HCE Systems.
  4. The pair of lights are blinking slowly. This indicates your heating system’s blower motor likely isn’t running. This component circulates hot air from the heater into your home. We can aid in determining what’s causing a problem with this component.
  5. A single light is blinking slowly and the other is blinking rapidly. This means your heating system may have insufficient voltage or a short circuit. Get in touch with our specialists at 276-302-0076 for assistance.
  6. One light is flickering on, on, off while the other blinks on, off, on. This indicates there may be a malfunction with your heating system’s control board or wiring. HCE Systems can pinpoint the error and repair it.
  7. The duo of lights are using every other slow blinks. This indicates your HVAC system possibly has a flame failure. There could be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 276-302-0076 for help.
  8. An individual light flickers slowly while the other stays steady. This typically means your HVAC equipment’s limit switch is malfunctioning. The switch stops your heating system from becoming too warm. Reach out to the specialists at HCE Systems for help.
