We have a Frigidaire side-by-side with the ice and water in the door. After having the refrigerator about a little less than a year we had to get a repair person out because the water stopped working. The appliance was still under warranty so it wasn't a big deal. The repair person told us that the water line in the door had froze up and he would replace the entire door to remedy the situation. Shortly after the warranty ran out it happened again. At that time we purchased Brita pitchers and kept them in the refrigerator because we were not going to keep paying for repair people to come out for a known defect with the appliance. After a hurricane and being without power for a couple of weeks, the door defrosted and the water worked again for about 6 months. Recently while scrolling through a site I saw a post about a Frigidaire side-by-side with the frozen water line in the door and someone recommended this product. I figured what did I have to lose. If it didn't work I'd return it; it was certainly better than paying for a repair person to come out and replace the door, and I was getting tired of being the only one to continuously fill that darn Brita pitcher. It arrived and I immediately got some of the hottest water I could from the tap, and went to work. I had to go through the process about 4 times, but after the fourth time water started coming out of the door again. I was so happy I could have jumped for joy on the spot!!! I understand the door will freeze again, but now I have this ready to remedy the situation immediately. I would definitely recommend this tool to anyone who may have the same situation. It is simple to use, works beautifully and is worth it's weight in the savings!!!!
