What Does the Flickering Light on My Heater Mean?

Your furnace uses lights to flash code when it is malfunctioning. It also engages this system to let you know it’s working correctly.

Regular operation includes:

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

If you see a single light going on and off slowly and the other going on and off rapidly, your heater could be experiencing a low flame signal. This can take place even when your furnace is running correctly. It indicates the flame sensing rod could have buildup or in the incorrect area on the burner. Contact us at 717-216-0846 for help.

Here are a few other of the most typical problems for Lennox HVAC systems.
