Help my Sundance Optima Spa keeping overheating during the filter cycle (every 6 hours) During the regular cycle, the blower jets are suppose to stay on only about 30 seconds, but ours keep running, then the spa overheats & eventually will turn itself off. We replaced the control panel but the problem still exists. It doesn't happen all the time, but it is becoming more frequent. We have the spa completely turned off because it always seems to happen when we are not home. Could it be the temperatur sensor? Help
