Aqua rite t-15 swg stopped making chlorine. All lights were off. Unit is 8 years old. When starting up, no flow light flashes for 45 sec, the generating sanitizer turns on for 10 sec, then all off. Before I read about the known issue with the current limiting varistor, I ordered a new pcb. I installed it and it still does exactly the same thing as the old board. Anyone have any ideas? Btw, the current limiter on the old board does look bad. Could the one on the brand new board also be bad?
