My Pentair pool heater is set at 98 degrees. The heater turns on fine, but it won’t shut off at the set temperature. I have replaced the sensor but it did not work.

If a pool heater is not turning off after it reaches the set temperature double check to make sure the automation system if you have one is set to the proper temperature. If the heater doesn’t turn off, its likely the motherboard. If it doesn’t physically turn off, the membrane itself needs to be replaced.
