Thanks to all of you guys!! Just like most of you have "hinted", I did buy a new one, same brand though, even before I posted this question. Calling a service guy would NOT be an option since it would cost half of the what I'll pay for a new one. The purpose of the question was really for me to understand how to diagnose it and did not really mean to be lazy and cheap. In Texas, yes, we have to inspect appliances and since I'm just beginning in this field, knowing how to diagnose one would somehow have an added value to my inpection service to my customers although I won't write on my report. I apologize if posting my question was inappropriate. Again, being new in this business (and on this forum), I did not mean to start off on the wrong foot. Alan
