While your Lennox® HVAC equipment isn’t able to chat with you, it possesses a procedure to get your attention when there’s a furnace error.

Its control board has double LED lights that can display a fault code. Based on the malfunction, your heater may use continuous or flashing lights.

What Does the Flashing Light on My Furnace Mean?

Your heating system uses lights to flash code when it is malfunctioning. It also engages this system to relay it’s operating like it should.

Normal operation involves:

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

If you see a solitary light going on and off slowly and the other blinking rapidly, your heater could be experiencing a low flame signal. This can take place even when your heater is operating like it should. It means the flame sensing rod might be dirty or in the incorrect location on the burner. Reach out to us at 308-995-8177 for assistance.

Here are some of the most common issues for Lennox furnaces.

Heater Won’t Kick On

Here are many of the light patterns you may notice when your furnace will not or keep operating. The majority of these problems have to be repaired by a technician, like one from Durable Service.

  1. Both LED lights are extinguished. This signifies your heating system might not be receiving power. Go to the breaker box to confirm the heater fuse isn’t flipped. You should reset the fuse if it’s in the “off” spot. If it promptly trips after a subsequent reset, don’t touch the breaker and get in touch with us us at 308-995-8177.
  2. A single light is unchanging and the other is flickering slowly. This shows the flame rollout switch is possibly not working right. The part is a critical safety guard that assists in preventing fires and carbon monoxide. You shouldn’t attempt to fix this problem without professional help.
  3. One light is blinking quickly and the other is flashing slowly. This often means power polarity has been inverted. Your heater might have a wiring issue that needs professional aid from Durable Service.
  4. Both lights are flashing slowly. This indicates your heating system’s blower motor likely isn’t running. This part moves warm air from the furnace into your rooms. We can help in figuring out what’s causing a problem with this part.
  5. One light is blinking slowly and the other is flickering fast. This indicates your HVAC system might have low voltage or a short circuit. Call our specialists at 308-995-8177 for support.
  6. One light is flashing on, on, off while the other blinks on, off, on. This signifies there may be a fault with your heating system’s motherboard or wiring. Durable Service can pinpoint the problem and take care of it.
  7. The pair of lights are using alternate slow flashes. This signifies your HVAC system may have a flame problem. There may be an issue with its gas supply, gas valve or ignitor control. Contact us at 308-995-8177 for assistance.
  8. A single light flashes slowly while the other remains continuous. This usually means your heater’s limit switch is malfunctioning. The switch stops your heating system from becoming too warm. Call the pros at Durable Service for help.
