While your Lennox® heating system can’t talk to you, it does have a process to communicate a furnace error.

Its control board has a set of LED lights that can share a fault code. Depending on the malfunction, your heater could display solid or flashing lights.

Although there are certain basic HVAC repairs you can do yourself, many tasks are best taken care of by the professionals. When your furnace will not turn on or put out heated air, get in touch with Assured Appliance & Heating & Air at 847-306-8990 for professional furnace repair in Genoa.

Our experts will swiftly discover and fix the breakdown, even if you don’t own a Lennox heater. We can repair whichever kinds or configuration—and get the warmth reintroduced to your residence without delay.

What Does the Flashing Light on My Heater Mean?

Your furnace uses lights to flash code when it isn’t working right. It also engages this system to relay it’s heating like it should.

Normal operation includes:

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

If you realize that a single light going on and off slowly and the other flashing fast, your heating system might be experiencing a low flame signal. This can take place even when your heating system is running like it should. It signifies the flame sensing rod may be dirty or in the wrong spot on the burner. Contact us at 847-306-8990 for support.

Here are several other of the most routine faults for Lennox heaters.

Furnace Refuses to Start

Here are some of the light arrangements you could observe when your furnace won’t turn on or keep running. Most of these issues must be repaired by a specialist, such as one from Assured Appliance & Heating & Air.

  1. The pair of LED lights are off. This indicates your heating system might not have power. Find the breaker box to ensure the heater fuse hasn’t triggered. Attempt to reset the fuse if it’s in the “off” position. If it instantly trips after a subsequent reset, don’t touch the breaker and call us at 847-306-8990.
  2. One light is continuous and the other is blinking slowly. This signifies the flame rollout switch is likely open. The part is an essential safety device that assists in avoiding fires and carbon monoxide. You shouldn’t seek to take care of this issue yourself.
  3. An individual light is flickering fast and the other is flickering slowly. This likely means power polarity has been reversed. Your heater may have a wiring fault that calls for professional assistance from Assured Appliance & Heating & Air.
  4. Both lights are blinking slowly. This indicates your heater’s blower motor likely isn’t operating. This part sends heated air from the heater into your home. We can assist in pinpointing what’s causing a problem with this part.
  5. An individual light is flickering slowly and the other is flickering fast. This means your heater may have insufficient voltage or a short circuit. Reach out to our technicians at 847-306-8990 for help.
  6. One light is flashing on, on, off while the other blinks on, off, on. This means there might be a fault with your HVAC system’s control panel or wiring. Assured Appliance & Heating & Air can locate the problem and fix it.
  7. The pair of lights are using alternating slow flickers. This means your heater possibly has a flame error. There may be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 847-306-8990 for assistance.
  8. A single light flickers slowly while the other remains steady. This often means your heater’s limit switch is malfunctioning. The switch stops your HVAC system from getting too hot. Call the experts at Assured Appliance & Heating & Air for help.

Furnace Blower Runs But No Warm Air
