What Does the Flickering Light on My Heating System Mean?

Your heater uses lights to flash code when it isn’t working right. It also uses this setup to relay it’s heating properly.

Normal function includes:

It indicates the flame sensing rod may have buildup or in the wrong spot on the burner. Call us at 254-307-9572 for assistance.
