    Unhappy Diffuser Position Fault in Chiller 19XR7272

    Hi Guys,

    Chiller is frequently tripping due to diffuser position fault while running.

    When I reset the Fault & switch on Chiller starts running.

    After sometime again the chiller Trips due to same diffuser position fault

    can anyone explain me the solution to solve this problem.

    How old is the chiller ? Are you over seas somewhere?

    First thing to do is to calibrate the diffuser ring drive motor, if that doesn't do the trick then the potentiometer usually has to be replaced and recalibrated. Good luck.

    Then you need to get the people who installed it to come out and make the issue go away.

    Call Carrier. If you mess this up, you will regret it.
