What Does the Flickering Light on My Heater Mean?
Your furnace relies on lights to flash code when it needs to be repaired. It also uses this setup to tell you it’s operating properly.
Regular heating involves:

This can occur even when your heating system is heating like it should. It signifies the flame sensing rod may have build-up or in the wrong spot on the burner.
