Check out the rubber ring ( or called door seal) to see if there is black mold build up inside the bottom rubble. 5 B$ X# Q5 U6 @0 b, I7 d7 i3 Z4 Z. n: _4 o* L- e, i9 X
If it does have mold and can not be wipe out, then you have to change out the whole seal.. I bought a new seal and changed out few weeks ago.
