Type of refrigerator: Whirlpool Gold Model No. GT19DKXJT00.

Purchased March, 2001. Problem started about one month ago. Happens
inside refrigerator. Both refrigerator and freezer continue to cool to
their normal temperatures and display no other problem.

PROBLEM DESCRIPTION: About every 24 hours roughly two thirds of a cup
of water leaks from the cooling vent in the rear of the refrigerator
onto the refrigerator shelves.

PLEASE NOTE: 1) The leak does not happen continuously. I have never
actually seen with my eye water drip from the air vent to the shelf.
The way I know this leak is coming from the vent is that I have placed
a cup on the refrigerator shelf under the vent and it catches the
water. 2) I don't know when the leak starts or when it stops. The
Care Guide for this refrigerator mentions a "self-defrost" cycle (page
19) but gives no details when this happens. I suspect it might happen
during this cycle.

Does anyone know what might be the problem? Any suggestion will be
much appreciated.
