    Trane hyperion trouble code

    I got a no cool call on a trane hyperion unit that we installed I was not there on the original install.

    The unit shut down indoor fan wouldn't even run. I go out their disconnect power and reconnect to unit. Unit starts up and everything is working I get a flash 6 or 7 times form the red fault light. Not having anything with me to tell me what the code is I check the refrigerant charge on a hunch and it was way under charged I am assuming that the valves were just opened but charge was never checked this is a two story house with probably 75 foot of line set.

    My question is Could the unit of shut itself off because of the EEV?

    When i initially checked charge the suction pressure was 95ish and the superheat was 50 degrees and subcooling was 1 degree

    I charged it to 10 degrees of subcooling

    It'll shut down after so many run cycles on certain faults.
    Read the service facts that comes with the unit. Find it.

    I got the service manual

    The code is high superheat so hopefully charging it up fixed it for good. I talked to the customer this morning and it was running fine. I am going to go back on friday and look at some air flow issues he has and verify it has no more codes

    Trane has a class for this type of unit. They basically read you the service facts and walk you through trouble shooting on airhandlers they have set up. Things you can pretty much do on your own if you have the service facts and a meter.

    Code six might be a few things depending on what led you're looking at.

    What is the model? TAM7, 8, or 4 or GAM5? GAM5 will have no blue LEDs.

    6 fault flash = valve not not responding to a position change.
    7 fault flash = high superheat.
    If charge was low sounds like 7 fault flash.

    So I got a call again Went back there the unit had power but everything was shut down.

    I Take the blower panel off and hold down the safety switches and it turns back on so I call the trane field service rep tell him what its doing. He asks me does it have the button door switches or the other style forgot what he called them. He said they had ran into issues with those not being depressed all the way and sometimes the unit wont work so I bypassed them in the mean time until I can get over to trane to get the new style switches.

    Which makes sense the newer hyperions I have installed have the other switches
