rk 2001U controller issues

[goodwood]

the digital readout on the controller will be at 175 , the Celsius guage will be over 100C, [which converts to 212F]. my overheat protection has started going on when the digital is at 180F,also sometimes the digital readout flickers between number changes and makes the fan speed up and slow down with the flickering, time for a new controller? its only 3 years old, or is there another solution
