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
