Hi There,
I am trying to confirm the fault code on a Hi-Wall Heat Pump - LG R18AWN-NC9 Indoor, R18AWN-UC9 Outdoor. Cooling LED flashes twice, Heating LED flashes twice.
Was unable to check the outdoor PC board because it was raining, but reset the isolator and unit ran fine, have not put gauges on yet as wanted to know what the fault code was first.
Thanks
