My air conditioner turns off after two hours then starts again por 15 or 20 minutes and turn off again. Although the air is off, it still has the lights on. Yesterday night, I turned off the air and after two hours, turn it on again. After an hour, it tuns off again with lights on. Is the compressor or is the Energy Saver function. I noticed the air in energy when I always use it in cool. Thank your
