What Does the Flashing Light on My Heating System Mean?

Your heating system relies on lights to flash code when it isn’t working right. It also engages this system to let you know it’s heating like it should.

Regular heating involves:

  • Concurrent slow flash—furnace operating properly.
  • Both lights flash fast—heating system is beginning to call for heat.

If you realize that a solitary light flashing slowly and the other blinking rapidly, your furnace might be experiencing a low flame signal. This can take place even when your furnace is working correctly. It means the flame sensing rod might be dirty or in the bad area on the burner. Contact us at 717-383-4479 for support.

Here are some of the most routine faults for Lennox heating systems.
