    Does it actually have low sh as tested or just looking at error alarms?
    If by a "Liberal" they mean someone who looks ahead and not behind, someone who welcomes new ideas without rigid reactions, someone who cares about the welfare of the people-their health, their housing, their schools, their jobs, their civil rights and their civil liberties-someone who believes we can break through the stalemate and suspicions that grip us in our policies abroad, if that is what they mean by a "Liberal", then I'm proud to say I'm a "Liberal.

    First, check every temp and pressure sensor in this unit, calibrate if necessary.
    Second, check for correct water flow and test expansion valve for correct operation.
    If you still couldn't find the problem, update us with data readings else helping is not really possible.
