Hello im new here and I have a sundance spa, sentry 800 from 1993.
Well when i turn on the breaker EVRYTHING turns on the jets and bubbles and only mode and the cycle button will work. You can not turn anything off. And after about 1 minute you see OH (over heated) appear on the screen and then everything shuts off and the control panal has 4 black lines going through it, and then nothing works.
I REALLY want to get this thing going on use it again. Any help is appreciated.
Thanks
