While your Lennox® furnace can’t chat with you, it does have a procedure to communicate a furnace error.

Its control panel has a set of LED lights that can display a fault code. Depending on the issue, your furnace could show steady or flashing lights.

Although there are certain simple HVAC fixes you can finish yourself, many fixes are best left to the professionals. When your heater will not turn on or deliver heated air, reach out to Parker County Cooling & Heating at 817-380-5213 for skilled furnace repair in Weatherford.

Our technicians will swiftly detect and fix the issue, even if you don’t use a Lennox heater. We can fix any brands or makes—and get the heat reintroduced to your residence without delay.

What Does the Flashing Light on My Heater Mean?

Your heating system relies on lights to flash code when it isn’t working right. It also engages this system to let you know it’s heating correctly.

Correct function includes:

  • Simultaneous slow flash—heating system operating correctly.
  • Both lights flash fast—heater is beginning to call for heat.

If you see a lone light going on and off slowly and the other blinking fast, your heater may be having a low flame signal. This can take place even when your heater is operating like it should. It indicates the flame sensing rod may need to be cleaned or in the wrong spot on the burner. Contact us at 817-380-5213 for help.

Here are some of the most routine issues for Lennox HVAC systems.

Furnace Will Not Kick On

Here are many of the light sequences you could observe when your heater won’t turn on or keep operating. Most of these problems have to be fixed by a technician, like one from Parker County Cooling & Heating.

  1. The pair of LED lights aren’t lit. This indicates your HVAC system might not have electricity. Look at the breaker box to ensure the furnace fuse is not triggered. Try resetting the fuse if it is in the “off” spot. If it immediately turns off after you reset it, don’t try to reset it again and contact us at 817-380-5213.
  2. A single light is unchanging and the other is flashing slowly. This shows the flame rollout switch is likely malfunctioning. The part is an essential safety device that aids in avoiding fires and carbon monoxide. You shouldn’t attempt to handle this malfunction on your own.
  3. One light is blinking rapidly and the other is blinking slowly. This likely signifies power polarity has been inverted. Your furnace could have a wiring error that needs expert aid from Parker County Cooling & Heating.
  4. Both lights are flashing slowly. This means your furnace’s blower motor probably isn’t running. This component sends hot air from the furnace into your rooms. We can aid in figuring out what’s causing a problem with this piece.
  5. One light is flashing slowly and the other is flashing quickly. This means your heating system might have insufficient voltage or a short circuit. Contact our experts at 817-380-5213 for help.
  6. One light is flickering on, on, off while the other flashes on, off, on. This indicates there might be a fault with your heating system’s motherboard or wiring. Parker County Cooling & Heating can find the fault and fix it.
  7. The duo of lights display every other slow flickers. This indicates your heating system possibly has a flame issue. There could be a problem with its gas supply, gas valve or ignitor control. Contact us at 817-380-5213 for assistance.
  8. An individual light flickers slowly while the other stays steady. This usually signifies your HVAC equipment’s limit switch is not working. The switch keeps your HVAC equipment from getting too hot. Reach out to the pros at Parker County Cooling & Heating for assistance.
