I am guessing you have a flame rod around the area of the pilot assembly. You have a sparker that makes that clicking sound. First off you have to make sure the pilot is clean and burning a good blue flame. This flame cannot lift off the pilot burner head, and it has to burn across the sparker to a ground plain. If it does not make contact like this. it will not turn the sparker off and it will not prove pilot flame, and act the way yours is. Clean all metal surfaces with fine sand paper, including sparker and ground plain. . Paul

hit or miss troubleshooting is the expensive way to go! a good tech would know what to do. be careful of this guy!
