While your Lennox® HVAC equipment cannot speak to you, it possesses a method to tell you about a furnace error.

Its control board has double LED lights that can show a fault code. Depending on the failure, your heater might display continuous or flashing lights.

Although there are various basic heating fixes you can do yourself, most repairs are best taken care of by HVAC technicians. When your furnace will not turn on or deliver heated air, call Allstar Heating & Air Conditioning at 805-242-9638 for experienced furnace repair in Buellton.

Our technicians will swiftly discover and fix the issue, even if you don’t have a Lennox heater. We can fix whichever kinds or configuration—and get the comfort returned to your residence without delay.

What Does the Blinking Light on My Heating System Mean?

Your furnace relies on lights to flash code when it requires repairs. It also engages these lights to let you know it’s heating properly.

Normal function consists of:

  • Simultaneous slow flash—furnace heating correctly.
  • Simultaneous fast flash—heater is starting to call for heat.

If you see a lone light blinking slowly and the other blinking rapidly, your heater may be experiencing a low flame signal. This can occur even when your heater is running correctly. It means the flame sensing rod may have buildup or in the wrong area on the burner. Reach out to us at 805-242-9638 for assistance.

Here are several other of the most common errors for Lennox HVAC systems.

Furnace Will Not Turn On

Here are a few of the light patterns you could observe when your furnace refuses to or keep heating. The bulk of these problems must be handled by a specialist, for instance from Allstar Heating & Air Conditioning.

  1. Both LED lights aren’t lit. This indicates your HVAC system might not be receiving power. Examine the breaker box to ensure the heating system fuse has not tripped. Try resetting the fuse if it is in the “off” area. If it promptly flips after you reset it, don’t touch the breaker and contact us at 805-242-9638.
  2. An individual light is continuous and the other is flashing slowly. This signifies the flame rollout switch is likely malfunctioning. The part is a critical safety device that aids in avoiding fires and carbon monoxide. You shouldn’t try to fix this problem on your own.
  3. A single light is flashing fast and the other is blinking slowly. This likely indicates power polarity has been reversed. Your heater may have a wiring error that needs expert aid from Allstar Heating & Air Conditioning.
  4. All lights are flickering slowly. This indicates your heater’s blower motor possibly isn’t running. This component circulates warm air from the HVAC system into your home. We can assist in figuring out what’s wrong with this piece.
  5. A single light is flashing slowly and the other is blinking quickly. This indicates your heating system could have low voltage or a short circuit. Get in touch with our experts at 805-242-9638 for support.
  6. One light is flickering on, on, off while the other flickers on, off, on. This indicates there could be a fault with your heating system’s control board or wiring. Allstar Heating & Air Conditioning can pinpoint the problem and handle it.
  7. Both lights show alternating slow blinks. This means your HVAC equipment may have a flame failure. There could be a problem with its gas supply, gas valve or ignitor control. Get in touch with us at 805-242-9638 for help.
  8. An individual light flickers slowly while the other remains steady. This typically indicates your HVAC system’s limit switch is not working. The switch keeps your HVAC system from becoming too warm. Call the professionals at Allstar Heating & Air Conditioning for help.
