While your Lennox® furnace isn’t able to speak to you, it does have a process to get your attention when there’s a furnace error.

Its control panel has a set of LED lights that can show a fault code. Subject to the problem, your heater could use solid or flashing lights.

When your heating system won’t turn on or provide heat, reach out to Allstar Heating & Air Conditioning at 805-242-9638 for professional furnace repair in Buellton.

What Does the Blinking Light on My Heating System Mean?

Your heating system uses lights to flash code when it isn’t working right. It also works this setup to tell you it’s working like it should.

Normal heating includes:

  • Simultaneous slow flash—heater operating like it should.
  • Both lights flash fast—furnace is initiating the call for heat.

If you notice a single light going on and off slowly and the other flashing rapidly, your heating system might be experiencing a low flame signal. This can take place even when your furnace is working properly. It signifies the flame sensing rod might need to be cleaned or in the wrong area on the burner. Contact us at 805-242-9638 for help.

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

Furnace Refuses to Start

Here are some of the light sequences you could observe when your heat will not or keep operating. Most of these issues must be taken care of by a professional, like one from Allstar Heating & Air Conditioning.

  1. The duo of LED lights are extinguished. This signifies your heater might not be receiving power. Find the breaker box to confirm the furnace fuse is not triggered. You should reset the fuse if it’s in the “off” position. If it instantly trips after you reset it, don’t try to reset it again and get in touch with us us at 805-242-9638.
  2. A single light is stable and the other is flashing slowly. This signifies the flame rollout switch is possibly open. The component is a critical safety device that assists in avoiding fires and carbon monoxide. You shouldn’t attempt to handle this problem without professional help.
  3. One light is flickering quickly and the other is flickering slowly. This typically signifies power polarity has been inverted. Your heating system could have a wiring issue that calls for specialized help from Allstar Heating & Air Conditioning.
  4. Both lights are flickering slowly. This indicates your heater’s blower motor probably isn’t running. This piece circulates warm air from the HVAC system into your house. We can assist in determining what’s causing a problem with this component.
  5. A single light is flickering slowly and the other is flickering fast. This means your heater might have insufficient voltage or a short circuit. Get in touch with our experts at 805-242-9638 for help.
  6. One light is blinking on, on, off while the other flickers on, off, on. This means there could be a fault with your heating system’s control panel or wiring. Allstar Heating & Air Conditioning can determine the problem and take care of it.
  7. The duo of lights display every other slow blinks. This means your HVAC equipment may have a flame problem. There could be trouble with its gas supply, gas valve or ignitor control. Get in touch with us at 805-242-9638 for support.
  8. An individual light blinks slowly while the other remains steady. This often means your HVAC equipment’s limit switch is malfunctioning. The switch stops your HVAC system from becoming too warm. Reach out to the specialists at Allstar Heating & Air Conditioning for help.

Furnace Blower Operates But No Heat

Here’s what might be broken when you notice your heating equipment’s blower fan working, but you aren’t gaining any warm air.
