replacement PCB board/mainboard /control board all tried and tested and we give 60 days warranty on all pre owned or refurbished parts. all parts are genuine. main reasons for replacing a board is a hot tub only heating up to a certain temperature and not getting any higher even when the desired temperature is set much higher. you can try a reset using the reset button on the side of the pump but very often the PCB is the culprit and replacing will resolve your issue.
