User Manual LG LP1311BXR 13,000 BTU Portable Air Conditioner

When the temperature reaches the thermostat setting, the compressor will shut off. It can be distracting, but this is the quietest unit I have had (tried three other brands/models before his one). Check to see if it also may turn off when the unit is getting too warm to avoid overheat. But if you feel that the unit is turning off improperly, contact the manufacturer or see about an exchange.

According to the tech I had out from LG they don 't recharge them and they charge $90 just to check them out. They did nothing on my unit which only worked for one season. I paid $750.
