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

Its control panel has two LED lights that can display a fault code. Based on the issue, your furnace could show solid or flashing lights.

Though there are certain elementary HVAC repairs you can finish on your own, the majority of repairs are best handled by experts. When your heater will not kick on or put out heat, reach out to Gee & Missler Heating & Air Conditioning at 734-284-1224 for skilled furnace repair in Wyandotte.

Our specialists will quickly detect and fix the problem, even if you don’t own a Lennox heater. We can fix whichever kinds or models—and get the warmth returned to your home quickly.

What Does the Flickering Light on My Heater Mean?

Your heater uses lights to flash code when it isn’t working right. It also works these lights to relay it’s operating correctly.

Correct function involves:

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

If you notice a single light going on and off slowly and the other blinking fast, your heating system may be experiencing a low flame signal. This can happen even when your heating system is working properly. It means the flame sensing rod might be dirty or in the incorrect area on the burner. Contact us at 734-284-1224 for help.

Here are a few other of the most typical problems for Lennox heating systems.

Furnace Won’t Start

Here are some of the light patterns you might notice when your heat won’t turn on or keep operating. Most of these errors need to be fixed by a professional, such as one from Gee & Missler Heating & Air Conditioning.

  1. The duo of LED lights are off. This means your heating system might not have power. Examine the breaker box to confirm the heating system fuse isn’t triggered. You should reset the fuse if it’s in the “off” area. If it immediately turns off following a reset, don’t try to reset it again and call us at 734-284-1224.
  2. One light is unchanging and the other is flickering slowly. This shows the flame rollout switch is possibly open. The part is an essential safety tool that aids in avoiding fires and carbon monoxide. You shouldn’t try to take care of this issue without professional help.
  3. One light is flickering quickly and the other is flickering slowly. This often indicates power polarity has been transposed. Your heater might have a wiring fault that needs specialized assistance from Gee & Missler Heating & Air Conditioning.
  4. The pair of lights are flickering slowly. This signifies your furnace’s blower motor likely isn’t operating. This piece moves warm air from the furnace into your space. We can help in determining what’s causing a problem with this piece.
  5. A single light is flashing slowly and the other is blinking quickly. This means your heater may have not enough voltage or a short circuit. Get in touch with our experts at 734-284-1224 for assistance.
  6. One light is blinking on, on, off while the other blinks on, off, on. This means there may be an issue with your heating system’s motherboard or wiring. Gee & Missler Heating & Air Conditioning can determine the fault and repair it.
  7. Both lights are using alternating slow flashes. This means your heater possibly has a flame issue. There might be a problem with its gas supply, gas valve or ignitor control. Contact us at 734-284-1224 for support.
  8. A single light flickers slowly while the other is continuous. This often indicates your heating system’s limit switch is malfunctioning. The switch keeps your HVAC equipment from overheating. Reach out to the pros at Gee & Missler Heating & Air Conditioning for assistance.
