E4 usually means either blocked capillary, low refrigerant charge, high ambient temperature.
First: check the filters. The front panel opens up like the hood of a car and the filters are fine plastic meshes that you should be able to see through. If you can't see through them that means they are clogged. pull them put and clean them with water only and replace. If the filters are blocked the unit will be unable to refrigerate properly.
Second: check the capillary (water outlet). If the hose is clogged, water usually backs up and sometimes the A/C will start dripping into the room. This also makes cooling defficient. Do NOT try to force water through the hose. Sometimes there is debris in it and you will just make the plug harder to remove. The way to remove it is by sucking the water back, not pushing it forward. A technician should be able to do this for you. The other possibility is that the other end of the "hose" (on the outside) is clogged or under water. Just remove the obstruction.
Third: the ambient temperatre is too high and your BTUs are not sufficient to cool the space. In other words, your A/C is not big enough for the amount of heat/size of the room.
Fourth: have the refrigerant level checked by a qualified technician. They can refill the refrigerant. They have all the tools required.
It sounds like you have a freon leak and may need a charge. When there is a leak, the compressor will run for awhile but without the proper charge, it will heat up and kick on on thermal overload. After the compressor cools, the unit will come back on. Have the unit serviced by a professional.
