小百兔,看看这个

别去折腾那个坏的.不容易找到控制线,FREON进出口径都MATCH的室内机. 室内机的EVAPORATOR容量也必须MATCH.

室内机一拆,FREON全跑了,还得重灌. the hassle/time/money is more than buying a new one.

consider buying a "PORTABLE" AC. it sits on the floor inside the room. It has a hose that goes through window (or a hole in the wall) to exhaust hot air. very easy to install - you do it yourself. slide the window for a crack. get a piece of foam plastic to fit the hose in the crack. works instantly. only downside is that the water pan needs to be emptied every day or two.
