WHIRLPOOL WRT519SZDW Ice Maker Not Working

Ice Maker Assembly

This modular unit contains an internal thermostat that must reach a specific temperature (typically 15°F) to close the circuit and initiate the harvest cycle. If the bimetal thermostat fails or the internal timing motor gears strip, the unit will never rotate the ejector arms to dump ice or signal the water valve to refill. Replacing the full assembly ensures all mechanical timing components and sensing elements are synchronized.

Water Inlet Valve

The water inlet valve utilizes a solenoid-actuated diaphragm to control water flow to the ice maker. Over time, calcium deposits or mechanical fatigue of the internal spring can prevent the valve from opening when energized, or the solenoid coil can fail due to heat stress, resulting in no water reaching the ice tray despite the ice maker attempting to cycle.

Water Inlet Tube

In top-freezer configurations, the fill tube that delivers water from the valve to the tray is prone to 'ice bridging' or total occlusion. If the water valve has a slight weep (slow leak) or if the freezer temperature fluctuates, small amounts of water freeze inside the tube, eventually forming a solid plug that prevents subsequent fill cycles from reaching the ice maker mold.
