Trying to defrost the water line in the refrigerator door I melted (deformed) the plastic parts.

I carefully removed the trim from around the dispenser area then freed the catches in the top of the electronic card. I leaned the card forward and disconnected the electrical connections, then removed the card. I removed the four screws holding the shield to the door and removed the shield. Then I removed the funnel from the shield and removed the spring from the old funnel and placed it on the new one. I removed the light and socket from the old shield and installed the in the new one, then installed the new funnel on the new shield, used the four screws to install the assembly on the door and replaced the trim piece.
