My dehumidifier keeps frosting/icing up (very, very thick buildup) on the coils and not melting and going into water pan. I currently wait until there is quite a build up then turn if off, the buildup melts, then I turn the unit back on again and repeat. Why is the build up not melting, I thought the room may not be warm enough to allow melting. The room is of normal temp about 72 degrees F. Could the cooling fan be moving the warm air away from the coils, so that the buildup cannot melt. This is only my logic, I am assuming this is part of the theory of how a dehumidifier is suppost to work. Could there be something mechinical wrong with the unit? Why is it building up ice and not melting??
