Answer: Could be very dirty and the lack of air flow is tripping the limit, could be the comp is seizing. This situation could be due to the cold air output gets sucked back immediately into the unit causing the thermostat to cut out. Make sure that the sponge seal between the outlet air and the return air is in place, it is just behind the front cover.
