My Aqualink had a bad front board for the Chlorine generator. Jandy no longer makes the board and they wanted me to replace the whole system for over $600 ! I looked on Ebay for my specific board and only a few were available. They few I did find, people were wanting close to $500. I ended up sending both my boards to Salt Solutions in Tampa and they tested both for free and ended up repairing the front board $175. The whole process, including shipping only 1 week. The system has been running perfect for the last 24 hrs so it appears they resolved the issue. Providing the board continues to work I highly recommend using this company if anyone gets in a similar situation. The board repair also came with a 12 month warranty.
