While your Lennox® furnace cannot talk to you, it possesses a method to communicate a furnace error.
Its motherboard has double LED lights that can display a fault code. Depending on the issue, your heater might display continuous or flashing lights.

Our technicians will swiftly identify and take care of the malfunction, even if you don’t own a Lennox heating system. We can fix whichever brands or configuration—and get the comfort reintroduced to your home fast.
What Does the Flashing Light on My Furnace Mean?
Your heater depends on lights to flash code when it isn’t working right. It also works these lights to let you know it’s operating like it should.
Regular function involves:
- Concurrent slow flash—heater running like it should.
- Simultaneous fast flash—furnace is beginning to call for heat.
If you notice a lone light flashing slowly and the other going on and off quickly, your heater may be experiencing a low flame signal. This can occur even when your heater is heating like it should. It indicates the flame sensing rod could be dirty or in the wrong location on the burner. Contact us at 717-216-0846 for help.
Here are several other of the most typical issues for Lennox furnaces.
Furnace Refuses to Start
Here are a few of the light patterns you may observe when your heat will not or keep heating. The bulk of these errors need to be fixed by a professional, for instance from County Line Mechanical LLC.
- Both LED lights aren’t lit. This means your heater might not be receiving power. Find the breaker box to confirm the furnace fuse has not flipped. You should reset the fuse if it’s in the “off” position. If it immediately flips following a reset, don’t try to reset it again and call us at 717-216-0846.
- One light is continuous and the other is flickering slowly. This signifies the flame rollout switch is possibly not working right. The part is an essential safety mechanism that helps in avoiding fires and carbon monoxide. You shouldn’t attempt to handle this problem without professional help.
- An individual light is flashing rapidly and the other is flickering slowly. This typically means power polarity has been transposed. Your furnace could have a wiring issue that needs professional support from County Line Mechanical LLC.
- Both lights are flickering slowly. This signifies your heating system’s blower motor likely isn’t operating. This piece circulates heated air from the HVAC system into your space. We can assist in determining what’s causing an issue with this component.
- An individual light is blinking slowly and the other is flashing quickly. This indicates your HVAC system could have insufficient voltage or a short circuit. Contact our experts at 717-216-0846 for help.
- One light is flashing on, on, off while the other flickers on, off, on. This signifies there could be a malfunction with your heater’s motherboard or wiring. County Line Mechanical LLC can find the error and fix it.

Furnace Blower Runs But No Heat
