    quick testing of the sensors only show open or shorted sensors. They could be way off. you need a manual for this chiller and study it.

    The inlet connection in circuit A and circuit B of the cooler has an oil and refrigent leaking due to rust.Can we change the cooling head or the inlet pipe to solve this problem or is there any other measures.
