there shouldnt be anything on a window unit that a vacuum could hurt but you might wanna be sure there is nothing like dirt dobber nest or something that might stop up your vacuum
SOURCE: my motor compressor thrifts every 5 mins.
If you have a low pressure switch on your air conditioner it's opening and closing, because you don't have enough refrigerant in the system or it's cycling on the thermal overload in the compressor because it's getting hot.
You need to charge your system to approximately 12° to 15° superheat not by pressure.

I have the same problem w/my CW-XC122VU. Other symptom is that the thermostat setting does not work in this "poltergeist" mode. After the problem went away by itself, then re-occurred, I notice it tracks the level of the water in the pan. A full pan of water will trigger poltergeist-mode, so I suspect some control or sensor is being shorted. The posted solutions ("transformer hum" or "broken on/off switch" are off the mark and generally unhelpful). We are not alone, though...the problem is observed in many Panasonic and Quasar window A/C units.
