While your Lennox® heating system cannot chat with you, it possesses a procedure to communicate a furnace error.

Its motherboard has a set of LED lights that can show a fault code. Subject to the failure, your heater might use solid or flashing lights.

Our technicians will rapidly determine and repair the breakdown, even if you don’t have a Lennox heating system. We can fix all kinds or models—and get the warmth returned to your residence fast.

What Does the Blinking Light on My Furnace Mean?

Your furnace depends on lights to flash code when it isn’t working right. It also uses these lights to relay it’s working like it should.

Regular operation consists of:

  • Concurrent slow flash—heater running like it should.
  • Concurrent fast flash—heater is starting to call for heat.

If you notice a solitary light going on and off slowly and the other blinking quickly, your heating system could have a low flame signal. This can happen even when your heater is heating correctly. It indicates the flame sensing rod might be dirty or in the incorrect spot on the burner. Contact us at 520-357-4912 for assistance.

Here are a few other of the most common problems for Lennox heaters.
