The most common issue in refrigerators typically revolves around the water inlet valve. When the water pressure in this valve is too low, it may fail to close entirely when the power is shut off. Consequently, the valve will leak water into the icemaker, leading to an overflow of ice in the icemaker compartment. Addressing this water inlet valve problem is crucial to prevent potential water leaks and ice maker malfunctions, ensuring your refrigerator operates smoothly and efficiently.
