While your Lennox® furnace cannot speak to you, it possesses a way to tell you about a furnace error.
Its control panel has two LED lights that can display a fault code. Based on the malfunction, your heating system might use continuous or flashing lights.

Our experts will swiftly determine and fix the issue, even if you don’t own a Lennox heater. We can service whichever types or configuration—and get the warmth reintroduced to your residence fast.
What Does the Flickering Light on My Heating System Mean?
Your heater depends on lights to flash code when it is malfunctioning. It also works these lights to let you know it’s heating correctly.
Regular operation includes:
- Simultaneous slow flash—heating system running like it should.
- Simultaneous fast flash—furnace is initiating the call for heat.
If you realize that a solitary light flashing slowly and the other blinking rapidly, your furnace could have a low flame signal. This can take place even when your heating system is working like it should. It indicates the flame sensing rod may need to be cleaned or in the wrong area on the burner. Call us at 239-214-0411 for assistance.
Here are some of the most common problems for Lennox heating systems.
Furnace Won’t Start
Here are some of the light patterns you could see when your heating system won’t turn on or keep heating. The majority of these problems have to be repaired by a specialist, such as one from Comfort Zone, LLC.
- Both LED lights are extinguished. This means your HVAC system might not be receiving power. Examine the breaker box to make sure the furnace fuse has not tripped. Try resetting the fuse if it’s in the “off” area. If it instantly turns off after you reset it, don’t try to reset it again and contact us at 239-214-0411.
- One light is continuous and the other is blinking slowly. This implies the flame rollout switch is may be open. The switch is an essential safety tool that helps in stopping fires and carbon monoxide. You shouldn’t try to repair this malfunction yourself.

Furnace Blower Works But No Warmth
