I have an old Jacuzzi hot tub. I have had the pump serviced, new heater installed and just replaced the heat sensors. The problem is that the hot tub is heating fine with the new heater, it is not shutting off at the set temp. it will keep running til it kicks off on "OH". Are there any other sensors,thermostats, or relays that might be bad?
