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

Its control board has a set of LED lights that can show a fault code. Based on the problem, your heating system might use steady or flashing lights.

Though there are certain simple furnace repairs you can complete without an expert, many services are best taken care of by experts. When your heater refuses to start or deliver warm air, get in touch with Farris Heating & Air at 918-333-0376 for expert furnace repair in Bartlesville.

Our experts will swiftly identify and repair the breakdown, even if you don’t own a Lennox heating system. We can fix all types or makes—and get the warmth returned to your residence fast.

What Does the Blinking Light on My Heater Mean?

Your heater relies on lights to flash code when it requires repairs. It also works this system to tell you it’s operating properly.

Correct operation consists of:

  • Concurrent slow flash—heater operating properly.
  • Both lights flash fast—furnace is beginning to call for heat.

If you notice a lone light blinking slowly and the other blinking fast, your heating system might be having a low flame signal. This can occur even when your heating system is running properly. It signifies the flame sensing rod could need to be cleaned or in the wrong area on the burner. Reach out to us at 918-333-0376 for help.

Here are a few other of the most typical faults for Lennox HVAC systems.

Furnace Refuses to Start

Here are some of the light sequences you could see when your heater will not or keep running. The majority of these issues must be fixed by a specialist, like one from Farris Heating & Air.

  1. Both LED lights are off. This signifies your heater might not have electricity. Look at the breaker box to ensure the heating system fuse hasn’t tripped. Try resetting the fuse if it is in the “off” spot. If it immediately flips after you reset it, don’t touch the breaker and get in touch with us us at 918-333-0376.
  2. One light is stable and the other is blinking slowly. This signifies the flame rollout switch is possibly malfunctioning. The part is an essential safety mechanism that assists in preventing fires and carbon monoxide. You shouldn’t try to take care of this problem yourself.
  3. An individual light is flickering quickly and the other is flashing slowly. This typically indicates power polarity has been transposed. Your heater may have a wiring error that requires professional help from Farris Heating & Air.
  4. The pair of lights are flashing slowly. This means your heater’s blower motor possibly isn’t operating. This component moves hot air from the heater into your rooms. We can help in figuring out what’s wrong with this piece.
  5. One light is flickering slowly and the other is flickering fast. This signifies your heating system could have insufficient voltage or a short circuit. Reach out to our technicians at 918-333-0376 for help.
  6. One light is flickering on, on, off while the other flickers on, off, on. This means there might be a malfunction with your heating system’s motherboard or wiring. Farris Heating & Air can find the problem and take care of it.
  7. The pair of lights are using alternate slow flickers. This indicates your HVAC system likely has a flame failure. There might be trouble with its gas supply, gas valve or ignitor control. Call us at 918-333-0376 for assistance.
  8. An individual light flashes slowly while the other is solid. This typically means your HVAC system’s limit switch is not working. The switch keeps your HVAC system from getting too hot. Get in touch with the pros at Farris Heating & Air for help.
