I have a 4year old Strong Spa that I purchased from Costco. I have loved it, but it recently started randomly shutting down, tripping the breaker. I have replaced the topside controller($300 ouch) and the heater unit($70). I have checked all connections....everything seems in place and tight.
I have unplugged each component to see if it is causing the shutting off.
Any help would be greatly appreciated.
Maybe irrelevant: The blower vent tube is broken off from the manifold.
