Replacing a relief valve is not something you do casually depending on what you guess you can do to solve a problem. The insurance company will want to be assured by a permission letter from the companies involved as to whether such a change is permissible under the pressure vessel codes.
I would really want to know what goes wrong with circuit boards to cause this problem that the circuit board control maker can't solve. Usually it is just a bad connection or a changed thermo-sensor.
