While your Lennox® HVAC equipment cannot speak to you, it has a way to tell you about a furnace error.

Its control board has twin LED lights that can show a fault code. Depending on the issue, your heater could use continuous or flashing lights.

Though there are a few elementary furnace repairs you can finish without an expert, the majority of repairs are best handled by experts.

Our experts will rapidly determine and handle the malfunction, even if you don’t use a Lennox heater. We can service all kinds or configuration—and get the comfort reintroduced to your residence quickly.

What Does the Blinking Light on My Heater Mean?

Your heating system depends on lights to flash code when it requires repairs. It also engages this system to let you know it’s heating like it should.

Correct heating involves:

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

If you see a solitary light going on and off slowly and the other flashing quickly, your furnace might have a low flame signal. This can take place even when your heater is working like it should. It means the flame sensing rod might need to be cleaned or in the incorrect spot on the burner. Contact us at 631-460-5159 for support.

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

Heating System Refuses to Start

Here are a few of the light sequences you might see when your heater will not or keep heating. Most of these problems have to be taken care of by a specialist, such as one from Fal-Ken Heating & Cooling Corporation.

  1. The pair of LED lights are off. This indicates your HVAC system might not have electricity. Examine the breaker box to confirm the heater fuse has not triggered. You should reset the fuse if it is in the “off” position. If it rapidly flips after you reset it, don’t touch the breaker and get in touch with us us at 631-460-5159.
  2. A single light is stable and the other is flashing slowly. This implies the flame rollout switch is likely open. The switch is an essential safety device that aids in preventing fires and carbon monoxide. You shouldn’t attempt to handle this problem without professional help.
  3. A single light is flashing rapidly and the other is flickering slowly. This often means power polarity has been reversed. Your furnace could have a wiring problem that calls for expert aid from Fal-Ken Heating & Cooling Corporation.
  4. Both lights are flashing slowly. This indicates your heater’s blower motor probably isn’t working. This piece circulates hot air from the furnace into your rooms. We can help in figuring out what’s causing an issue with this part.
  5. A single light is blinking slowly and the other is flickering quickly. This indicates your HVAC system could have insufficient voltage or a short circuit. Get in touch with our specialists at 631-460-5159 for assistance.
  6. One light is flashing on, on, off while the other flashes on, off, on. This indicates there could be a fault with your heater’s control board or wiring. Fal-Ken Heating & Cooling Corporation can locate the error and handle it.
  7. The pair of lights show alternate slow flashes. This indicates your HVAC equipment possibly has a flame failure. There may be a problem with its gas supply, gas valve or ignitor control. Contact us at 631-460-5159 for help.
  8. A single light flashes slowly while the other remains solid. This usually indicates your heater’s limit switch is malfunctioning. The switch prevents your HVAC system from getting too hot. Reach out to the professionals at Fal-Ken Heating & Cooling Corporation for assistance.

Heating System Blower Runs But No Warm Air

Here’s what could be wrong when you observe your heating system’s blower fan on, but you aren’t gaining any heated air.

  • The duo of lights are giving every other quick blinks. This means your furnace ignitor could be broken. This piece ignites fuel in your HVAC equipment to create warm air and should be fixed by a specialist from Fal-Ken Heating & Cooling Corporation.
