    Question low oil flow latching alarm

    hi every one,

    i am facing an diagnostic issue in my RTAA 217 trane chiller with low oil flow alarm first i thought that came to my mind was that oil filter was dirty hence hence 1) i changed the oil filter along with new oil but still problem persist,

    2) then i checked for differential pressure switch since the diagnostic alarm is "low oil flow" then in order to check wether the DPS is working properly or not i changed DPS ..........but still the problem continues

    plz advice.......

    You would have saved money and time if you would have called someone that knew how to work on a RTAA. Also would have helped if you put this in Chillers not Residential.
