If you are searching for the GE WR49X10173 part then you’ve probably determined that your water line is frozen on your GE refrigerator. This is a very common problem for GE side by side refrigerators. Typically your ice maker is still making ice and you’ll hear a “click” when activating the water dispenser.
This water line heater attaches to the water dispenser control panel in about 15 minutes. It keeps the line warm enough to keep it from freezing again. For $30 you can’t beat it! I also purchased a new water filter (below) as it had been about 5 years since I replaced it. Amazon has the best prices for both these parts.
Also, if you need help thawing the frozen line before you insert the heater, we recommend the water line buddy to shoot warm water up the frozen line. Always good to get the XL version as you never know how far up the line is frozen.
