We have included a drop-down below to help you locate your heater temperature sensor cable by your spa system control system part number. If your Balboa system part number is not included in the drop-down below, it means that your temperature sensor has been discontinued by Balboa. If that is the case, we suggest that you feel free to give us a call and we will assist you in locating a generic replacement.  You can reach us via chat, telephone, or e-mail.  We are here to help!
