Frozen water supply line: need parts break-down and installation instructions over use of WR49X 10173 Heater add-on kit so I can engineer, construct, and make my own kit to install for less money: GE wants over $70.00 USD for the kit. The greedy bastards should have a recall that includes the fix for this defect, free! Never will I purchase another GE product, including even a CFL!
