shorembo Posted April 29, 2012 Report Share Posted April 29, 2012 It seems that the heater on my hot tub will not turn off. As an example, the water temperature is at 80. I set the temperature to 70. The water heats up. After awhile it is at 100+. I check the temperature setting and it is 70 but the water temp is now 100+. I have a spa with a Balboa G2 circuit board. I checked the resistance on both temperature sensors and they registered fine. Any ideas? Quote Link to comment Share on other sites More sharing options...
