A dehumidifier is mostly an window unit that is inside the room. When it is working, cool air should come out the on/off side and hot air out the other side, with water collecting. If that doesn’t happen, it isn’t working.
They are more often throw-aways when they don’t work as repairs are close to the cost of a new one.
