What Does the Flickering Light on My Heater Mean?

Your heating system depends on lights to flash code when it isn’t working right. It also uses this system to relay it’s heating like it should.

Regular heating involves:

  • Simultaneous slow flash—furnace working correctly.

If you realize that a solitary light blinking slowly and the other going on and off fast, your heater may be having a low flame signal. This can happen even when your heating system is running like it should. It indicates the flame sensing rod might be dirty or in the bad location on the burner.
