I have an Aqua Logic Board and Hayward Tcell940 (2 years old)
When the clorinator count down ends I hear a click and immediately the check system light comes on.
I took the cell to leslies - PASS and it's clean
I replaced the circuit board. (same error but now with a 1 on the end "Check system no cell power 1")
I took the old circuit board to saltsolutions in tampa and he told me the board is good.
Fuses have been checked with a volt meter.
What am I missing? Please give me a clue. thanks!
 
Replaced rectifiers and the check light is staying off.
My chlorine is good right now.
I'll check in 24 and see if it holds.
PS We are novice electricians. Novice! Replacing the board took about 1 hour. (the second time 20 minutes) If we can do so can you. Before you start write down the all of the settings. (Salt solutions guy in Tampa was great. He tested the board and the salt cell. If I had a board that need tlc I'd go to him/mail to him.
