Installed a new Sta Rite 400HD towards the end of January. Followed installation instructions exactly, and it has been working wonderfully till 2 weeks ago. The control membrane was freezing up and the heater was turning on all by itself, so I decided to have a pro come out and diagnose it for me. He quickly discovered corrosion on the backside of the control board that is mounted inside the heater housing. I asked if it was an issue with installation, he said the installation was fine and that he has seen this issue with this heater numerous times. Since I installed the heater myself, Pentair will not honor any form of warranty, so I ordered a replacement control board and keypad membrane to repair myself.
I would love to hear some info from anyone who's dealt with this already. My biggest concern is that it is only a matter of time before the next board develops corrosion and shorts. I am attaching some pics below of the back of the board and the corrosion is pretty easy to see. Does anyone know of some sort of electronic water proofing spray that I could coat the board with in order to avoid future corrosion issues? Or is that a terrible idea?
Again, any information would be more than welcome, and thanks in advance!
