Are foreign materials on rubber gasket?
Reason
Rubber gasket on the refrigerator door is maintained elastic for adherence.
However, when there are foreign materials on it, elasticity or adherence may be lost.

If a part of the rubber gasket is detached, apply gradual heat with a hair dryer to straighten.
※ When using the hair dryer, keep appropriate distance of about 1 span.
