What Does the Flickering Light on My Heater Mean?

Your furnace relies on lights to flash code when it is malfunctioning. It also engages these lights to tell you it’s working properly.

Normal operation consists of:

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

If you see a solitary light going on and off slowly and the other going on and off quickly, your furnace might have a low flame signal. This can occur even when your heater is heating like it should. It indicates the flame sensing rod could have buildup or in the incorrect area on the burner. Reach out to us at 203-357-5913 for help.

Here are some of the most typical issues for Lennox heating systems.
