While your Lennox® HVAC equipment can’t chat with you, it has a procedure to get your attention when there’s a furnace error.
Its control panel has a set of LED lights that can share a fault code. Subject to the fault, your heating system could use solid or flashing lights.

What Does the Blinking Light on My Heating System Mean?
Your heater depends on lights to flash code when it requires repairs. It also works this setup to tell you it’s heating like it should.
Normal heating consists of:
- Concurrent slow flash—heater heating properly.
- Both lights flash fast—furnace is starting to call for heat.
If you see a lone light blinking slowly and the other flashing quickly, your heater might be experiencing a low flame signal. This can happen even when your heating system is running like it should. It means the flame sensing rod could have buildup or in the wrong spot on the burner. Call us at 208-621-0129 for assistance.
Here are some of the most common faults for Lennox heaters.
Heating System Won’t Kick On
Here are some of the light arrangements you could notice when your heat refuses to or keep heating. Most of these issues have to be fixed by an expert, like one from Vogts Heating & Air.
- The pair of LED lights are extinguished. This indicates your HVAC system might not be receiving power. Find the breaker box to confirm the heating system fuse is not tripped. Attempt to reset the fuse if it’s in the “off” position. If it promptly trips after you reset it, don’t touch the breaker and call us at 208-621-0129.
- A single light is continuous and the other is flickering slowly. This implies the flame rollout switch is possibly open. The switch is an essential safety mechanism that helps in preventing fires and carbon monoxide. You shouldn’t attempt to handle this fault without professional help.
- A single light is flashing quickly and the other is flashing slowly. This often means power polarity has been inverted. Your heater may have a wiring issue that needs specialized help from Vogts Heating & Air.

Heating System Blower Runs But No Warmth
