What Does the Flashing Light on My Heater Mean?

Your furnace uses lights to flash code when it isn’t working right. It also engages this system to relay it’s heating like it should.

Correct heating consists of:

  • Simultaneous slow flash—heater heating correctly.
  • Simultaneous fast flash—heater is beginning to call for heat.

If you realize that a solitary light flashing slowly and the other flashing fast, your heating system could be experiencing a low flame signal. This can take place even when your furnace is working correctly. It means the flame sensing rod might need to be cleaned or in the incorrect location on the burner. Contact us at 410-228-4822 for support.

Here are some of the most common errors for Lennox HVAC systems.
