While your Lennox® furnace isn’t able to chat with you, it does have a method to get your attention when there’s a furnace error.
Its control panel has two LED lights that can show a fault code. Subject to the fault, your furnace might display continuous or flashing lights.

What Does the Blinking Light on My Heating System Mean?
Your furnace relies on lights to flash code when it isn’t working right. It also engages this system to tell you it’s working properly.
Normal heating consists of:
- Concurrent slow flash—heater operating properly.
- Simultaneous fast flash—furnace is starting to call for heat.
If you realize that a single light going on and off slowly and the other blinking quickly, your heating system may be having a low flame signal. This can happen even when your heater is operating properly. It signifies the flame sensing rod may have buildup or in the incorrect spot on the burner. Contact us at 484-646-3363 for help.
Here are some of the most typical errors for Lennox heating systems.
Furnace Will Not Kick On
Here are a few of the light patterns you might see when your furnace will not or keep operating. The bulk of these issues have to be taken care of by a specialist, like one from Moyer Total Indoor Comfort.
- The duo of LED lights aren’t lit. This means your heater might not have power. Find the breaker box to make sure the heater fuse isn’t tripped. Attempt to reset the fuse if it’s in the “off” spot. If it immediately turns off following a reset, don’t touch the breaker and call us at 484-646-3363.
- One light is stable and the other is flickering slowly. This implies the flame rollout switch is likely open. The switch is a critical safety mechanism that aids in stopping fires and carbon monoxide. You shouldn’t seek to take care of this malfunction on your own.
- One light is flickering fast and the other is flickering slowly. This likely indicates power polarity has been inverted. Your heater could have a wiring error that requires professional help from Moyer Total Indoor Comfort.
- Both lights are flickering slowly. This indicates your heater’s blower motor likely isn’t running. This part moves warm air from the heating system into your home. We can help in pinpointing what’s wrong with this component.
- An individual light is blinking slowly and the other is blinking fast. This means your heater could have low voltage or a short circuit. Contact our experts at 484-646-3363 for help.
- One light is flickering on, on, off while the other flashes on, off, on. This means there might be trouble with your HVAC system’s control board or wiring. Moyer Total Indoor Comfort can find the fault and fix it.
- Both lights show alternating slow blinks. This indicates your HVAC system possibly has a flame failure. There may be a problem with its gas supply, gas valve or ignitor control. Contact us at 484-646-3363 for help.
- A single light flashes slowly while the other stays solid. This typically signifies your HVAC equipment’s limit switch is malfunctioning. The switch keeps your heater from becoming too warm. Call the specialists at Moyer Total Indoor Comfort for support.
Heating System Blower Works But No Heat
Here’s what might be wrong when you notice your heater’s blower fan on, but you aren’t gaining any warmth.
