If you own a Maytag or Amana refrigerator with an ice and water dispenser in the door, keep reading. Amana and Maytag have used a Y-connector in their refrigerator water supply tubing. This connector brought two water lines into one, and is located right after the fill valve. The Y-connector can be in the icemaker or chilled water lines, or both. This connector has had problems with leaking and, even worse, breaking and is now no longer available.
