My sundance spa stopped heating...the control board light that says heat does not light up ...but it did up until today and stayed warm. The flow light does come on and work as well as everything else. I have noticed over the past couple of days the reset button on the side of the heater was tripped...even though tub did not reach max temp...but once I reset it worked fine...any help would be great. I checked board for with tester and I am getting power to board for heater relays but nothing coming out....is my board fubar?
thanks
