Its control panel has double LED lights that can show a fault code. Subject to the issue, your heater may use continuous or flashing lights.

What Does the Blinking Light on My Heating System Mean?
Your heating system relies on lights to flash code when it isn’t working right. It also works this system to relay it’s operating like it should.
Normal function involves:
- Simultaneous slow flash—heating system operating correctly.
- Simultaneous fast flash—heater is beginning to call for heat.
If you realize that a lone light going on and off slowly and the other blinking quickly, your heating system could have a low flame signal. This can take place even when your heating system is working correctly. It signifies the flame sensing rod could be dirty or in the bad location on the burner. Contact us at (337) 234-2345 for support.
Here are a few other of the most typical faults for Lennox furnaces.
Furnace Won’t Turn On
Here are a few of the light patterns you might see when your heat will not or keep running. The bulk of these problems need to be taken care of by a professional, such as one from AC Sales.
- The duo of LED lights aren’t lit. This indicates your heating system might not be receiving power. Find the breaker box to ensure the furnace fuse has not flipped. You should reset the fuse if it’s in the “off” area. If it promptly trips following a reset, don’t try to reset it again and call us at (337) 234-2345.
- A single light is unchanging and the other is blinking slowly. This shows the flame rollout switch is may be not working right. The part is an essential safety device that assists in preventing fires and carbon monoxide. You shouldn’t try to fix this malfunction without professional help.
- A single light is blinking fast and the other is blinking slowly. This likely means power polarity has been transposed. Your furnace could have a wiring error that calls for expert assistance from AC Sales.
- The pair of lights are flashing slowly. This signifies your heating system’s blower motor likely isn’t running. This piece moves warm air from the furnace into your rooms. We can aid in determining what’s causing an issue with this component.

- One light is flashing on, on, off while the other blinks on, off, on. This means there might be a fault with your heater’s control panel or wiring. AC Sales can determine the fault and handle it.
