I had similar problem once. A spider got fried onto the on/off contact switch and kept the unit from turning off. Solution: Cleaned switch.

YOUR UNIT CAN ALSO BE OVERCHARGED OR HAVE AN EXPANSION VALVE THATS NOT ALLOWING THE PROPER AMOUNT OF FREON TO PASS.

Hi, Sounds like its low on refrigerant. Could also be restricted air flow inside. Turn the AC off and the inside fan on for about 3-4 hours to thaw out the evaporator. Replace the inside air filter. If you can see the side of the evaporator that the air goes into, check to see if it has a blanket of fuzz on it. If so, It can be cleaned with a credit card while its wet by scraping along with the fins. Turn the AC back on and let it run for about 20 minutes. The large line outside should sweat all the way to the compressor but the compressor should stay mostly dry. There may not be anything wrong with you unit. When it is cooler at night they will sometimes freeze if the thermostat is turned down too low during the night and the air restriction will not let it thaw during the day. Hope this helps. kstfas
