As I've explained repeatedly this year, the move to "electronic codes" to make trouble shooting 'easier' . . . doesn't. The pool industry does not have master mechanic manuals (like you get for autos) that explain EVERY code, and how to respond.

Instead, most of the codes are unexplained in any source I've been able to find. So my moderate knowledge of gas fired pool heaters is useless since I've never worked on a RayPak 406a -- I'd need product specific service info I don't have, and don't seems to have access to.

There are a LOT of people here who know "what's going on" with pools, but very few of them have a RayPak 406a -- and to be a little blunt, most of us don't waste our time reading through long posts, once we hit the reference to electronic "codes" -- we already know enough about what's going on, to know that it's not likely that we can help.

So, we move on to someone else, who we can help.
