The motor went in my valve head. (3 port mid position valve). I replaced that. system still didn't work (hot water works ok with manual override). I got a circuit diagram from internet and found - through a long drawn out detection process that one of the microswitches had burned out. However, its not a good diagram and doesn't exactly fit my system. My question is has anyone attempted to replace these switches and is there a good site to learn more about the electrical side of the system? (I'm loathe to buy a complete new valve head). thanks glenn
