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

Its control panel has a set of LED lights that can share a fault code. Depending on the malfunction, your heating system may show steady or flashing lights.

Although there are some basic heating adjustments you can do yourself, the majority of fixes are best left to experts. When your heater will not start or give warmth, call Childress Heating & AC at 540-675-4306 for skilled furnace repair in Fredericksburg.

Our experts will rapidly discover and take care of the malfunction, even if you don’t have a Lennox heating system. We can fix all brands or models—and get the warmth returned to your house fast.

What Does the Flashing Light on My Heating System Mean?

Your furnace depends on lights to flash code when it is malfunctioning. It also uses this setup to relay it’s heating properly.

Correct function involves:

  • Concurrent slow flash—heating system operating like it should.
  • Simultaneous fast flash—heating system is beginning to call for heat.

If you see a solitary light going on and off slowly and the other blinking fast, your heater could be having a low flame signal. This can happen even when your heater is working like it should. It indicates the flame sensing rod might be dirty or in the incorrect spot on the burner. Reach out to us at 540-675-4306 for assistance.

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

Furnace Will Not Start

Here are a few of the light patterns you may notice when your heat won’t turn on or keep heating. The bulk of these issues have to be taken care of by a technician, like one from Childress Heating & AC.

  1. All LED lights are off. This means your heater might not have electricity. Look at the breaker box to make sure the heating system fuse has not triggered. Try resetting the fuse if it is in the “off” area. If it rapidly turns off following a reset, don’t touch the breaker and get in touch with us us at 540-675-4306.
  2. An individual light is unchanging and the other is flickering slowly. This implies the flame rollout switch is possibly open. The component is a critical safety guard that aids in preventing fires and carbon monoxide. You shouldn’t attempt to handle this malfunction without professional help.
  3. A single light is flashing quickly and the other is flashing slowly. This often signifies power polarity has been inverted. Your furnace could have a wiring fault that needs expert help from Childress Heating & AC.
  4. Both lights are blinking slowly. This indicates your heater’s blower motor likely isn’t operating. This component distributes warm air from the furnace into your house. We can help in determining what’s wrong with this piece.
  5. One light is blinking slowly and the other is flickering fast. This means your heater might have low voltage or a short circuit. Get in touch with our experts at 540-675-4306 for help.
  6. One light is flashing on, on, off while the other flickers on, off, on. This signifies there could be a fault with your HVAC system’s motherboard or wiring. Childress Heating & AC can pinpoint the issue and take care of it.
  7. The duo of lights show alternating slow flashes. This indicates your HVAC equipment may have a flame problem. There could be a problem with its gas supply, gas valve or ignitor control. Call us at 540-675-4306 for assistance.
  8. A single light blinks slowly while the other stays steady. This often indicates your heating system’s limit switch is not working. The switch keeps your HVAC system from becoming too warm. Get in touch with the pros at Childress Heating & AC for help.
