I am on my second board for the Mineral Springs SWG, which as I understand, is an Aquarite (Goldline) re-branded product. I replaced the board last year because the previous one burnt out and replacing the Termistor did not solve the problem. Now, the Thermistor has fried again after 2-1/2 months of service this year. I'd like to know if anyone has an idea why this keeps happening and if there is anything I can do to prevent the issue. In this case, it burnt out after I performed a routine cleaning of the filter cartridge and Hayward t-15 salt cell. I am turning power off at the main breaker while performing the cleaning. Any ideas?
