I bought 2 of these wall ACc about 3 years ago with a year year span, The model numbers are slightly different but overall model is the same.
This year, I noticed a black liquidy substance on the grates and cleaned it. Then I took the grates off and saw black dirt n the styorfoam and it went all the way down to the fan wheel. Is it mold? What's creating it after three years?

It's the accumulation of dust that get's wet. You can take it out of the wall and use a garden hose to clean it out. Just make sure it's dry before you put it back and turn it on.
