why does the drain pan of my window a/c unit keep getting clogged with goo causing the water to drain into the room instead of outside?
Kenmore, Mod: 580.75050500, Ser: 412TAKK17173, 5150 Btu Window air conditioner, about 3 to 4 yrs old. It worked fine for the first year and a half and ever since I have to pull it out of the window about every three to five weeks, remove the shrouds and clean the styrofoam drain pan of a greenish, somewhat clear goo that plugs up drains. A narrow channel from the front (room side) to the back of the unit always plugs up first. When this happens the water drips into the room and mold mitigation is becoming a problem. How do I prevent the goo from growing? Why does it do this now and not when the unit was under warranty. I am not so rich that I can afford to replace an otherwise good working a/c with a new one that will probably do the same thing.
