While your Lennox® HVAC equipment can’t talk to you, it does have a procedure to get your attention when there’s a furnace error.

Its motherboard has twin LED lights that can show a fault code. Depending on the fault, your furnace could display solid or flashing lights.

Though there are various elementary HVAC repairs you can do yourself, many tasks are best taken care of by HVAC technicians. When your furnace will not turn on or deliver warm air, contact The Frazier Company at 402-628-0206 for professional furnace repair in Omaha.

Our specialists will swiftly detect and handle the problem, even if you don’t own a Lennox heater. We can repair all kinds or models—and get the warmth returned to your residence fast.

What Does the Flashing Light on My Furnace Mean?

Your furnace relies on lights to flash code when it requires repairs. It also uses this system to relay it’s operating correctly.

Normal operation consists of:

  • Concurrent slow flash—heating system working like it should.
  • Both lights flash fast—heater is starting to call for heat.

If you realize that a single light flashing slowly and the other blinking fast, your heater may be having a low flame signal. This can occur even when your heating system is running like it should. It signifies the flame sensing rod may be dirty or in the wrong area on the burner. Call us at 402-628-0206 for assistance.

Here are some of the most common problems for Lennox heating systems.

Heating System Won’t Turn On

Here are many of the light sequences you might observe when your heat won’t turn on or keep heating. The majority of these problems must be fixed by an expert, such as one from The Frazier Company.

  1. The duo of LED lights are extinguished. This means your heating system might not have electricity. Go to the breaker box to make sure the heater fuse is not triggered. Try resetting the fuse if it is in the “off” area. If it promptly turns off after a subsequent reset, don’t try to reset it again and get in touch with us us at 402-628-0206.
  2. An individual light is stable and the other is flickering slowly. This signifies the flame rollout switch is possibly not working right. The part is a critical safety guard that helps in stopping fires and carbon monoxide. You shouldn’t attempt to handle this problem without professional help.
  3. A single light is blinking fast and the other is flickering slowly. This likely signifies power polarity has been inverted. Your heater might have a wiring error that calls for professional aid from The Frazier Company.
  4. The duo of lights are flickering slowly. This indicates your furnace’s blower motor possibly isn’t running. This part distributes heated air from the heater into your rooms. We can help in figuring out what’s wrong with this piece.
