What Does the Flickering Light on My Heater Mean?

Your furnace depends on lights to flash code when it is malfunctioning. It also works this system to let you know it’s operating like it should.

Correct operation includes:

If you realize that a single light blinking slowly and the other going on and off fast, your heater might be experiencing a low flame signal. This can take place even when your furnace is running properly. It indicates the flame sensing rod might be dirty or in the incorrect spot on the burner. Contact us at 281-231-8768 for assistance.
