What Does the Flashing Light on My Heater Mean?

Your furnace uses lights to flash code when it isn’t working right. It also works these lights to tell you it’s heating properly.

Normal operation includes:

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

If you see a lone light going on and off slowly and the other going on and off quickly, your furnace may be experiencing a low flame signal. This can happen even when your heater is heating properly. It indicates the flame sensing rod could be dirty or in the wrong spot on the burner. Contact us at 641-316-9803 for help.
