I have a Jandy LT 400N-L heater that was installed with the pool was rebuilt in 2005. It has never worked right. It would run fine for a few months then begin to shut off within a few minutes after igniting. I had some "Authorized" service people out who first said it was a pressure switch problem, charged me for a new switch after which the problem would come back a month or so later. Another service man put in a new flame sensor, but that didn't help. I am getting a flashing light next to the "pressure switch" indicator. I'm pretty handy with most things but I'm not sure where to start looking for the problem. Anyone out there familiar with this model and this problem?
