From another site..we are also having same problem! 2003 Sears Kenmore Top Freezer Refrigerator(Frigidaire built)(Model#25363722300): Leaking water in refrigerator section in defrost cycle, Needs upgraded ferrule, part#240365901, replaced, worked great.
This part is used in the evaporator section, it tunnels the defrost water to the defrost drain in the back control panel trough, down through drain line to the bottom drip pan.
The complaint the customer will say is happening is that defrost water is dripping on the top glass shelf of the Refrigerator Section.
Ferrule
