While your Lennox® heating system cannot chat with you, it possesses a method to communicate a furnace error.

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

Though there are a few simple heating adjustments you can do without an expert, most fixes are best handled by the professionals. When your heating system won’t kick on or provide warmth, call SKC AC LLC at 432-203-4881 for skilled furnace repair in Big Spring.

Our specialists will speedily determine and handle the malfunction, even if you don’t use a Lennox heater. We can repair any brands or configuration—and get the comfort reintroduced to your house without delay.

What Does the Blinking Light on My Heater Mean?

Your furnace depends on lights to flash code when it requires repairs. It also engages this setup to relay it’s working properly.

Correct operation involves:

  • Simultaneous slow flash—heating system operating like it should.
  • Simultaneous fast flash—furnace is initiating the call for heat.

If you notice a single light going on and off slowly and the other going on and off rapidly, your heater could be having a low flame signal. This can happen even when your furnace is heating correctly. It signifies the flame sensing rod might need to be cleaned or in the bad spot on the burner. Contact us at 432-203-4881 for assistance.

Here are some of the most typical faults for Lennox HVAC systems.

Furnace Refuses to Turn On

Here are a few of the light patterns you could notice when your furnace will not or keep operating. The bulk of these problems have to be handled by an expert, like one from SKC AC LLC.

  1. All LED lights aren’t lit. This means your heater might not have power. Go to the breaker box to confirm the heater fuse isn’t tripped. You should reset the fuse if it is in the “off” area. If it rapidly flips after you reset it, don’t touch the breaker and get in touch with us us at 432-203-4881.
  2. One light is continuous and the other is blinking slowly. This implies the flame rollout switch is likely not working right. The switch is an essential safety mechanism that aids in preventing fires and carbon monoxide. You shouldn’t try to repair this fault without professional help.
  3. An individual light is flickering rapidly and the other is blinking slowly. This typically signifies power polarity has been inverted. Your furnace might have a wiring fault that calls for specialized aid from SKC AC LLC.
  4. The duo of lights are flashing slowly. This signifies your heater’s blower motor likely isn’t running. This part moves warm air from the furnace into your house. We can aid in figuring out what’s wrong with this component.
  5. An individual light is blinking slowly and the other is flickering quickly. This indicates your heater might have not enough voltage or a short circuit. Get in touch with our technicians at 432-203-4881 for help.
  6. One light is blinking on, on, off while the other blinks on, off, on. This means there could be a malfunction with your heater’s control board or wiring. SKC AC LLC can find the fault and handle it.
  7. Both lights are using alternating slow flashes. This indicates your heater may have a flame error. There may be a problem with its gas supply, gas valve or ignitor control. Reach out to us at 432-203-4881 for help.
  8. A single light flashes slowly while the other stays steady. This often indicates your heater’s limit switch is not working. The switch keeps your heating system from overheating. Reach out to the experts at SKC AC LLC for assistance.

Heating System Blower Runs But No Heat

Here’s what might be at fault when you observe your heater’s blower fan running, but you aren’t receiving any heated air.

  • The pair of lights are giving alternate rapid flickers. This means your furnace ignitor could not be in working order. This component lights fuel in your furnace to make warmth and should be serviced by a technician from SKC AC LLC.
