We just bought a 2004 J-345 Jaccuzi from a private owner. He stated the controller just went blank one day. I hooked it up and everything powered up perfectly. However, when I checked it 20 minutes later there was no power; display was blank, radio would not come on, circuit breakers not tripped. When I manually tripped and reset the circuit breaker the spa came back on for another 20 minutes or so then kicked off again. Has anyone experienced this? Wouldn't a bad sensor indicating an over temp showing up on the display rather than just shutting it down? Seems like some part of the circuit is heating up and opening then cooling down and working again. Transformer? Thank you
