Non-cooling Our 38AKS016/40RM016 split system is cooling a 24' X 60' room which has 4 open doorways to three other areas (cooled by different units). The room has ~30 PC's and 2 printers which are on continually. Sometimes when the outside temperature is below 30F, the system gets in a mode where the air mover runs, but the compressor does not. The room will equilibriate about 8 degrees above the temperature set point (71F) and the compressor will not come on until it warms up outside (or the system is recycled). Any ideas?

If your electronic thermostat is located in the room of indoor unit then the actual temperature of the room where your air out supply cannot be sense by your electronic thermostat. The sensor of your electronic thermostat is inside the electronic thermostat itself. So you need to install that in the room that you are cooling.
To check if the unit have adequate refrigerant charge, check the suction pipe of your outdoor (the big pipe) if sweating or if you have the thermometer check the temp. of the pipe it should be from 50 to 60 deg. F. If it is higher than this or if the suction is dry you need to add refrigerant.
