Check out the rubber ring ( or called door seal) to see if there is black mold build up inside the bottom rubble. ! P$ P3 ^- f7 i5 [/ D4 X0 B! e- q- @9 V, l1 ~" d
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.
