Water top shelf of refrigerator seems to keep coming back
Typer: Roper
Model:RT21LMXKQ03

If this is a top freezer model, the water can be coming from one of two things.
1. Leaking refrig. Door gasket
2. the freezer drain is stopped up and water from defrost is overflowing into the refr. Section.
Look in the back of the freezer section toward the bottom to see if ice has built up around the air duct.
