Leaking Dometic ice maker

I just got through replacing my supply line in a 2000.....it came out in pieces like a broken windshield...many, many pieces. I believe the problem is with the heater wire that runs next to it and the heat destroys the plastic over time, especially when the water is turned off and the fridge is still used. It was no biggie to do, but had to pull the fridge out and that is a pain..280 pounds. I actually used a moving dolly and built a pedestal on it so I could slide the fridge out on it and roll it into an area that gave me access to the rear. The sheath that the water line and heater ran through was not able to be used again so ran both through some clear tubing to keep the water line warm. Good Luck!!
