What Does the Flickering Light on My Furnace Mean?

Your heater relies on lights to flash code when it is malfunctioning. It also engages this system to tell you it’s heating correctly.

Regular operation consists of:

  • Simultaneous slow flash—furnace heating correctly.
  • Concurrent fast flash—heater is starting to call for heat.

If you see a solitary light going on and off slowly and the other going on and off fast, your heater might be having a low flame signal. This can take place even when your furnace is working like it should. It indicates the flame sensing rod could be dirty or in the wrong location on the burner. Contact us at 949-204-0859 for support.

Here are several other of the most routine issues for Lennox heating systems.
