What Does the Flickering Light on My Furnace Mean?

Your heating system depends on lights to flash code when it is malfunctioning. It also engages this setup to tell you it’s heating like it should.

Correct heating involves:

  • Simultaneous slow flash—furnace operating like it should.
  • Simultaneous fast flash—furnace is beginning to call for heat.

If you see a lone light going on and off slowly and the other flashing quickly, your heating system could be having a low flame signal. This can occur even when your heating system is running like it should. It signifies the flame sensing rod might need to be cleaned or in the incorrect location on the burner.
