What Does the Flickering Light on My Heating System Mean?

Your heater depends on lights to flash code when it isn’t working right. It also uses this system to let you know it’s heating properly.

Normal heating involves:

  • Concurrent slow flash—heater working correctly.
  • Both lights flash fast—furnace is beginning to call for heat.

If you see a solitary light flashing slowly and the other going on and off fast, your furnace might be having a low flame signal. This can happen even when your heating system is heating like it should. It means the flame sensing rod could have buildup or in the incorrect location on the burner. Call us at 614-879-9091 for assistance.
