My Kenmore room AC spews

misterbb I have the same thing happen with the LG in my office. I took the unit out, then took it outside, sprayed the front and back coil will Greased Lighting or dishwashing detergent mixed with water and washed it down with a garden hose. What is happening if like mine is that the dirt and such has built up on your fan blade, condenser coil, and evap coil and the unit just needs a good cleaning. I use to work in a shop in Texas where we did a lot of window units and cleaning was just part of the job. The coils should be bright and blade clean. Also if you take the cover off you should oil the fan motor with a light weight household oil. Hope this helps.
