I have a master spa MS2000 p/n 52958 i was getting a sensor

Customer Question

i have a master spa MS2000 p/n 52958 i was getting a sensor B code on the display. when i swapped sensor A and B the problem remained on the display as sensor B. i was told it meant a bad board. i ordered the exact replacement board and installed it. now
i am getting an OHH code. the pumps never cut on and the tub is full. when i disconnect one of the sensors,and plug it back in, the pumps kick on for a little bit ( 3 or so mins ) and cuts off again. the control panel is non responsive. what do you think my
problem is? Thanks,

OHH is a temperature sensor failure code.
The sensor provably needs to be replaced
to clear this trouble.
