Well after changing the circulator pump and both of the thermistors I was back in business and all was well for about 3 weeks now she's tripped again. Back in what appears to be that limit shut down state. Good grief! Cycled power a couple times... nada. Gonna open it up tomorrow for a look-see... Anyone have any ideas for what I should be looking for? Update... after removing the plug for the LED lights and cycling power on I get the circulator pump running and the control unplugged light is now on but the heat light is not on.

Thank you... it was in fact the circulator pump. I replaced the pump. All is good now thank you so much for your help!

I have problem where entire spa shuts down. No panel lights or function. No heat or ozonator. Only blinking blue panel illumination light (not signal lights). After overnight power down it came back up and seemed to work normally (verified panel, ozonator, and jets worked... didn't wait for heat) After draining and refill, it's back to same issue. Short power cycling of just a few minutes have no effect. Power is being received on both circuit boards. Thank you!
