Frozen Fridge drain line update

Re the Kenwood top freezer plugged/frozen defrost drain line. Removed the ice maker and interior rear and bottom panels. thawed/removed ice at bottom of coils. Melted/cleared ice from drain line by using a 'turkey baster' squirting/sucking hot water in about five minutes. Wound about five loops around defrost heater element with very pliable #12 stranded copper wire extending the wire about six inches down the defrost drain. Hopefully the wire will carry enough heat during the defrost cycle to keep ice from reforming in the 'neck' of the drain line.
Thanks to those offering suggestions and helpful ideas.
