I have a Whirlpool White Conquest Side-By-Side Refrigerator GS6SHAXLQ03, manufactured March 2003. The ice maker creates ice and fills the "holding bin" on the interior of the door. However, when one puts a cup against the dispenser to get ice out of the door, nothing comes out (the water works fine). The problem seems to be that the ice in the holding bin sticks together, forming a block of ice that cannot get through the ice dispenser. It starts sticking on the bottom and in a couple of days is a completely frozen block. Is there a way to stop the ice from sticking and forming a block so that we can get ice out of the door? Thanks, John D.
