回答“Why won't my GE refrigerator dispense water?”My water line has frozen up a few times recently. I figured that a life of frequent defrosting wasn't going to work for me. After Further investigation I found that the ice flapper was slightly open freezing the protruding water line. The rubber flapper actually came off its holder slightly. After watching a you tube video on how to remove the front panel (simple) to gain access to the "flapper" I was able to reset the flapper on its holder. I'm certain that my frozen water line is solved until the next time someone jams an object in the Ice chute in an attempt to free the stuck ice. So before you go and rewire and purchase heating kits I would suggest checking or changing the "flapper".
