Customer Question

Good day. I have a Paradise 40 spa purchased in 2001. It is currently unable to maintain the temperature setting. While we set it to 102F the setting shown on the Control Center increases and the heat level of the water goes up to corespond with the setting. While most times you can reset the temp setting downward back to 102 often the control pad is locked out when the spa hits 107F our higher and the only way to reset the spa is to turn off the power and then turn it back on. Any suggestions as to how to resolve this problem would be greatly appreciated.

It sounds like a bad controller or sensor. Without ohming the resistance it is hard to tell. The temp rises due to this defect and then the high limit sensor trips and locks out unit. Do you have a meter and know how to perform a resistance check?

Thank you Billy. Yes, I have a meter but do not know how to use it on my tub.
Expert:  Billy replied 6 months ago.
ok,we have 2 options.... 1 - you take a short study on how to read resistance with a multimeter and understand the readings. 2 - you call for service to have a tech ohm sensors and change if one is bad (which is my bet)

Billy, I think you missunderstood me. I know how to use the meter but have no idea as to where I would attach it on the spas components.
