What Does the Flickering Light on My Heating System Mean?

Your heating system relies on lights to flash code when it is malfunctioning. It also works this system to tell you it’s heating like it should.

Correct heating consists of:

  • Concurrent slow flash—heating system operating properly.
  • Concurrent fast flash—heater is starting to call for heat.

If you realize that a single light blinking slowly and the other flashing quickly, your heating system might have a low flame signal. This can occur even when your heating system is running properly. It means the flame sensing rod might be dirty or in the wrong location on the burner. Contact us at 713-364-9957 for assistance.

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

Heating System Won’t Kick On
