text: There is a temperature probe that controls the compressor. It is usually located on the front of the air condition and it senses the temperature of the air coming into the machine. \nthere are a few things you can do if you want the room cooler.\n\n1) clean the air conditioner, take it out and wash it. make sure the fins are free of dirt and dust. If you can see through them and the look shiny, they are probably clean.\nAlso clean the sponge filter in front\n\nIf any of these are dirty you will not get good airflow and the machine will not cool properly.\n\n2)check to see that the machine in not icing up. if there is too much of a buildup of ice the compressor will also shut off.\nthis is also usually caused by lack of airflow.( clean it!)\nalso make sure the unit is tilted back so the water if flowing out of it properly.\n\n3) turn down the temperature knob. is it at its lowest setting?\nyou can tell what the room temp is by twisting the knob, you will hear a click when it goes by the room temp.\n\n4) move the cool air fins so they direct air away (usually up and to the side a bit) from the A/C unit. sometimes if they are directed down, the unit starts sucking in the air it just cooled, and make it think the room is cool.\n\nThe compressor does have an overheat setting, but if the unit is clean, there should be no reason for it to overheat.\n\ntry turning the unit to the med setting, so that it should run longer at a lower fan speed. that could also help.\n\nThe only other thing I can think of is if the temp sensor went bad,\n\nand remember usually A/C units are made to that the lowest temp is about  18 dgrees C or about 65 degrees F\nit is not made to cool a room more than that.\nAll else fails, call sers service. They have an 800 number.\nbut it is different for different areas, look it up in the phone book \nunder Sears parts and service.
