While your Lennox® HVAC equipment cannot talk to you, it does have a way to communicate a furnace error.

Its motherboard has two LED lights that can share a fault code. Depending on the issue, your heater may use continuous or flashing lights.

Our experts will rapidly discover and fix the issue, even if you don’t own a Lennox heater. We can fix all kinds or configuration—and get the heat returned to your home without delay.

What Does the Flashing Light on My Heater Mean?

Your furnace depends on lights to flash code when it requires repairs. It also uses this system to let you know it’s heating correctly.

Regular heating consists of:

  • Concurrent slow flash—furnace operating like it should.
  • Both lights flash fast—furnace is starting to call for heat.

If you notice a single light flashing slowly and the other blinking quickly, your heater could be experiencing a low flame signal. This can take place even when your furnace is working like it should. It indicates the flame sensing rod could have buildup or in the bad location on the burner. Contact us at 847-306-8990 for support.

Here are some of the most typical errors for Lennox furnaces.
