I have done too many to name repairs and replacements on our 99 Sundance Cameo. Recently there was no power to the top side controller(6600-803) so I flipped the circuit breaker off and on, and there was power to the top side. This didn’t last long, though. I was still getting power to the spa itself, but nothing to the top side. After turning the power off I pried the controller off to see it had been burned out(photo enclosed). Everything looks right on the main circuit board, so I’m hesitant to purchase a new top side controller before hopefully getting more advice. Any help would be greatly appreciated.
