I'm new to the forums and new to pool ownership. I just purchased a home that has a nice pool and spa and I'm having an issue with the Jandy Aqualink RS Control System not tuning one of my valves, causing my spa to drain in spa mode. I had someone from Leslie Pools come out to take a look at it and said it's not the valve that was defective, but it could be control board that needs to be replaced. He told me the cost was going to be $1,500 for the part plus the labor to install it. First, I don't want to spend that kind of money on something that could be the problem and second, I've done some research online as to what these cost and it seems I can get an entirely new system for less than that.
Is there any way that I might be able to do something myself to check validity of what the service tech told me, and if the control board is the issue, get some recommendations of online stores where I may be able to purchase one for cheaper than $1,500?
