my portable air conditioner, dirt like browish stuff, help!
Hello, I have a portable air conditioner which I have not use for almost 2 years, recently I have plug it back in and use it. Everything works well.
Except one problem..
In the back of my portable air conditioner, it have a little square box container like build in where we can put back the Power Cord plug.The function of that box is just to storage the power cord, since the power cord is kind of long.
Now the box is empty since I plug in the power cord.
But since last couple of days, I notice inside that box keep falling out "some dirt like browish soft stuff", it is soft, so I think it just dirt.
But then it seem like it falling out from somewhere inside my portable air conditioner.
What can this be? Acid? My AC is working fine, what can i tbe then?
Any help is appreciated. Thank you
