My Jandy LX heater fires up and runs fine.......but after a while, it shuts down and stops heating.......but with no codes or error light. I noticed it stops at ~92 degrees. I have it set at 99 degrees, but can change it all I want and the heater won't come back on. If I wait a day, it will fire up again, but the same problem occurs.
I suspect a limit switch or something like it, but I would expect a error code. The maintenance manual is zero help, and I've googled all over the forum and web and can't find anything.
