The Whirlpool WPW10485955 Ice Machine Pump Harness is an essential component for keeping your refrigerator's ice machine running efficiently. The ice maker's pump is connected to the electrical system of the appliance via a tangle of wires. The pump, which is in charge of bringing water into the ice maker to produce ice cubes, receives electricity from this harness. A malfunctioning pump harness can cause insufficient or no ice production in your refrigerator. Your ice maker's functionality can be restored with a somewhat easy repair: replacing the defective pump harness. There are more advantages to having a working pump harness than just having access to ice. It guarantees that your refrigerator's water WPW10485955 dispenser, which generally uses the same water line as the ice maker, functions correctly.
